JDMvW, May 15, If the moths are alive you'll want a long working distance such as afforded by the mm Jerry mentions. There is also the nice Nikon micro zoom on the used market.



Both these lenses are not cheap. Both the mm and the mm zoom will require extension to get you to the about 2: This can be unwieldy: I need between I mention Kenko because their tubes are chipped, unlike Nikons, so they allow meter coupling to the lens.



For example I can get 1 cm full frame with my D the 50mm and mm of extension. Since the front of the lens is only a few cm from the subject this setup would NOT work well with live subjects, nor will on-camera flash work - you'll need the bracket or a ring.



I don't know of a bellows that allows meter coupling but I could be wrong. Without that, macro flash is not as convenient. I also find bellows in the field do-able but a pain. If alive expect to be deleting a lot of images before getting a good shot!



Edwin Barkdoll, May 15, Extension tube, bellows and the like do OK in image quality, especially with the original lens reversed, but are much less convenient, at least in my opinion.



Getting a real macro lens is really preferable, but hardly justified unless you are going to do a lot of close-up work. By the way, many longer telephoto even zoom lenses have a so-called "macro" function that is really just "close focus".



If you don't need to go to 1: Erik, can you tell us more about what he is shooting - free moving in the wild, dead with a pin in its back etc - and what lenses he already has?



This info can help guide any suggestions. JDM makes some good points. Diopters close up lenses I would definietly recommend the multi-element lenses like the Nikon 5T and 6T over single element lenses as there can be a significant difference in quality.



Stacking both a 5T and 6T on the micro gets me only to about 1: For that reason I usually use extension when shooting around x: I simply can't get there with diopters alone with the micro lens I have.



Just as a bit of an aside, here is a flash bracket rig I put together for macro work using two Nikon SB They are controlled by the Ds in commander mode via CLS. I also included a quick release for the camera, and add one on the bottom for a tripod or monopod.



The bracket and mini ball heads came from Adorama. This is a quick shot with the rig. I reduced both flash units to half power. The question here is about the working distance and available light.



Tripod, cable release and a lens in reversed position could be more than enough for an occasional shot. If going for a longer lens you'd lose to much DOF for a subject like this so i think mm or mm on acrop sensor..



The mm VR micro is a very versatile lens so it is not wasted when using it for other work too in my opinion.. They will allow full AF and Metering. The mm VR would allow a degree of framing stabilisation and a reasonable working distance.



From some very limited experience Moths are less 'flighty' Sorry than Butterflies and allow a somewhat closer approach. Depending on the subject, if the animal is a bit elusive, the longer the better; you can succesfully use a mm tele lens with an extension tube to make things "easier".



The mm would worry me with being too short for a moth, unless it's dead. If you can afford it, I'd consider something like the mm or mm Sigma macro lenses not from personal experience - I'm still lusting after one.



I suspect the OS would help with framing even if you use a flash, if you're after a mobile subject. This is where experienced macrophotographers who do everything with focussing rails and stacking software start laughing at me - although depth of field is not going to be your friend with a 1cm target.



As for filling the frame with 1cm, that's tricky and into Canon 65mm MP-E territory. Short of reversing rings or bellows, I might start asking why you need to fill the frame.



If it's just about pixel count, sticking a 90mm Tamron or mm Tokina, or mm Sigma on a D and just cropping the middle off the sensor might work as well as trying to fill the frame with a D90, and might cost less than exotic longer macros although working distance will always help.



Andrew Garrard, May 16, I have a D90 and the Sigma mm non-OS version. I highly recommend this lens. I have been using natural light up to now, but just picked up the R1 closeup flash system with 2 SB Wish I could comment on the flashes, but have only had a chance to use it once.



Posted a reply which has not appeared First of all, thanks for all your full responses, they have given me a lot to think about. The mm looks ideal but too expensive for the occasional use that it will get.

To save on price, one option is to go with a reputable second hand dealer, like KEH. Could save a couple of bucks that way. Has anyone done filters for these yet? This is a great comparative piece, though, for UV lenses, and if nothing else gives you a feel of brands to trust.



Before buying any non-kit lens for A, I think it should be a good idea to check, if you have Lightroom, with the pictures took with the kit lens mm to see what is the focal you use the most. You would be surprised with the result!



Take a big bunch of photo in your LR Library, see all the metadata of the complete bunch, the you see all the focal you used. Also if possible maybe a new feature would be to compare flashes? Pretty much the only way that springs to mind to get a bit more light in is to adapt a lens from another system, either one with an already faster aperture, or using a Speed Booster adapter, which lets a camera capture more light.



Autofocus in low light is always a hard thing. Mirrorless cameras are getting better at this slowly and the newer crop of cameras claim to be able to catch focus in some pretty low light conditions.



But until then, yeah, getting better with MF will serve you pretty well. Body upgrading would also be tricky. Pretty much the only slightly better option out there for you right now is the Sony a though it does have a greatly improved AF system.



If you want anything more substantial, you have to push into the A7 territory, which is full frame, and a whole different ballgame. I wanted a mirrorless camera for the portability.



Do you think I should get it or not? And how important do you think a zoom is for travel photography? I also have some canon DSLR lenses. Do I need an adaptor for those, and are there any drawbacks to using them like no autofocus?



All of which would benefit from having a long zoom around. Some are better quality than others, some might lose some optical quality, or drop AF speed. I would never go on a trip with just a prime. You would have such limited options with framing and composing.



I just got the a with the Does not seem bad but it distorts so much at 16 you can correct in post. The convenience of not switching lenses is priceless. Why most photographers use those expensive f: Get a, maybe a grey market model, it will cost you less than 2 primes and be more flexible.



Get an adapter for you Canon primes and use manual focus the Sony viewfinder highlights what area is in focus. You could buy some used fast prime, After all primes are usually used in less hectic situations.



I have a question about the first lens listed. So is this basically recommending a 50mm lens as a good general use lens? If i wanted a 35mm lens would I be looking for a You have it exactly right!



Olympus and Panasonic use Micro Four Thirds, which is smaller still, and uses a 2x crop factor, so would need a 25mm lens to reach 50mm equivalence. You conclude for that category of lenses that the Sony is the most balanced.



Was this taking the price into consideration? With the price being almost equal should I definitely take the Zeiss over the Sony? I tried it for a week compared to kit lens and Sony native primes.



Just disappointed because its quality is similar to the kit lens while at 2. Perhaps the m silver or the G? The Sony E mm is also noticeably softer and displays significantly more vignetting and distortion.



CA control is quite good, however. Most of the time, primes are going to give you a better result, due to only having to be good at one focal length rather than a bunch.



Thanks for your reply Tim. Indeed that Sigma range would have been perfect for walk - around even as subs of the wider prime as you suggested, however the wish and hunt will continue. Perhaps I am being too harsh on the Z from my non-professional testing.



I will do some more digging before sending it back. Though i ordered the 32mm Touit just now in replacement before the promotion runs out of time. So how do u like the Z since u had it awhile?



The color renderings are superb. However, it was the sharpness - i was being overly critical on this small sized zoom lens. I think that i will have this lens on for most of time out as my walk around - Zeiss and F1.



Now since I know both of those lenses are really top notch I have a hard decision to make. I would for sure rather get the Flexibility matter way more than absolute lens quality for taking photos.



You are out and about. You want to take photos of something or someone you encounter. You may want to get some wide shots to give context. You may want to get some detail shots. You may want to take a good portrait as well.



A prime like the 32mm will not be wide enough for establishing wide shots. Otherwise too much fiddling switching lenses, that also increases the risk of dust on the sensor and dropping something.



I am considering the Zeiss for my alpha a The kit does not seem bad, but the distortion at 16mm is a joke lightroom corrects it but it crops the edges. Zooms allow taking of better photos, better composition, better interaction with random subjects.



But sometimes I like carrying a 20mm or a fast 35mm with my nikon. Absolutely the is the perfect range for out and about. Perhaps one day i will give it another try.



My ideal would be the mm plus a 60mm or 70mm fast prime. I hope your having a good day. Such a great write-up, thank you! The Sony also seems a bit smaller and with me traveling, it is something that is a nice feature, but not a deal breaker.



Which lens do you think would be the better one to go after with my current skill being pretty new? But for what you need, notably the stabilization, size, and possibly faster AF, I think it might be more useful for you.



So I think the Sony would serve you fairly well. Thanks for the quick reply! I guess to clarify one point, if video was taken out of the equation, but the other factors still played into the decision, does that change the recommend?



You can probably get away without the IS by instead using the fast aperture and cranking the ISO a bit. For the video stuff, I think it depends a lot on how you shoot.



Thanks so much for the input, it really is appreciated! The Sony 35mm and Sigma 30mm lens are not available where I live. What would you recommend — Sony 16 mm F2. Debating which lens to get if at all.



I have the kit lens that came with the alpha and the sigma 30 mm. I am going on a 2 month hiking trip and any equipment i bring will be on my back so I am trying to keep the weight down.



I believe i will want a mixture of nature photography and street photography. I can take 2 small relatively lightweight lenses or one slightly heavier more versatile lens.



What do you guys recommend? Just depends what you want more! Not sure which lens i should get, so i need your help! I use a sony a, and i currently have the kit lens that came with it mm, the 50f1.



I love the 50f1. Should i be getting a shorter focal length instead? But thanks for the advice! Was maybe going to get some sort of steady thing for it too. I just got the A Planning to get Zeiss.



But lenses are a lot more expensive than Nikons but will get an adapter ring to mount some old Nikons like a fast 35mm prime. If you shoot events and conventions you need a lens like the Fiddling with primes under pressure is a pain.



If you shoot portrait work in the studio primes are great. I purchased a 2nd hand pankcake lens which is great when you want to throw it in your pocket when out for drinks and dinner.



I have started using flickr again…you can find me here https: Ok — thanks for letting me know. Im thinking I might invest in the 55 — mm then a prime lens like the 35mm — which i heard is great in low light..



Eminently sensible move, I say go for it. Hi Tim, unfort — here in europe there is quite a big difference in price between the 2. This blog is class and is my go to place for E mount lens info!!!



Either the 35mm or 50mm lens will give you pretty solid results, you just will have to shoot from a bit of a distance. Any of these lenses will work with the a, so pick whichever one sounds good to you, and fits your budget!



Thank you Time for replying…. I will appreciate if you can mention any specific model. Very helpful and informative. I am considering venturing in to the interchangeable lens e-mount world, and have been eyeing up the NEX range for several years now.



Currently I only take iPhone photos but want more from my amateur photography. I have recently been using a Sony QX30 for work and love the ability to pair with my iPhone.



And if so, might as well get the one with the kit lens included, so you have something to shoot with. Thanks for the super prompt reply. Yes, there is definitely a lag with the QX30, which is mainly due to the way it transfers via wifi from camera to phone for preview.



For work, I mainly use the QX30 to take photos with 30x optical zoom photos from an extension pole mount remote shooting. Personal use of the QX1 would be totally different, rapid shot portraits of my kids, mainly.



I need to see how the lag is affected if I turn off the 2 second preview. My main concern was whether there was any reason to think the e-mount on the QX1 was in any way limited?



Lag aside, should I expect the same performance and image quality and lens compatibility? Hmmm…the rapid shot portraits might be tricky to pull off due to the delay. As for the mount?



However, there are some other caveat. Hello, first of all, thanks for the amazing write-up! My friends recommend that I should just get the mm zeiss. Should I also consider getting the mm? Do I need any prime lenses?



What would be most suitable for the needs I mentioned above? My budget is around 1k They take amazing photos, but are very advanced, and every one of them has its own series of strengths and weaknesses that you need to be aware of when figuring out which to buy.



The mm will be a go anywhere, do anything lens. The Zeiss would instead replace your kit lens that usually comes with the a So you could get the a with just the body, and then pick up the Zeiss, since it does the job of the kit mm but better.



Great info here, I was given a Sony A with no lenses long story I use a bridge camera with a long zoom currently. I shoot a lot of landscapes and portraits too.



Will the 35mm 1. If you want something affordable to use for landscapes, the Sigma 19mm is a great option. Great article I really enjoy it. You said 50mm on a mirorless is equalvalent to 75mm, so when it comes to portrait which one is a better choice?



Can I say 32mm on a mirorless crop sensor is equalvalent to 57mm? The crop factor on an APS-C camera is around 1. So a 32mm lens gives you an equivalent focal length of 48mm. Only way I would shoot with primes is if I would carry 2 cameras.



I bought the Zeiss grey market for Anyway I am spoiled by old Nikon glass. If you have a A, it is cheaper to buy the Sigma 19mm and the Sony 50mm 1. Cameras are small enough to have 2 with primes in the bag.



A cheap adapter for Nikon F lenses is good too. I do not want to rent the modem. Do I need the router too? Also, which is best TL or Arri s? I mainly use the camera for product reviews so I like to have good shots of devices and use it for video recording as well.



Any suggestions would be helpful. While Sony is really small and portable and having a wider angle, the Sigma has better image-quality overall. Which one would you recommend? Is the size and weight that much of a difference?



I am searching for a new lens to do a couple things: I was thinking about the 35mm or the Sigma 30mm fir that, would that be right? So much to learn! The 35mm will give you the ability to blur the background more due to its wider maximum aperture, if that makes a difference.



I just bought an A after considerable reading dumping my SLR and lenses, ugh. I have a few questions. First, I have been reading many posts that rate the 50mm 1. Your info on the 50mm makes it seem quite a niche lens.



Still the same outcome after time has passed? Secondly, with the choices above and your consideration of enhancing the kit lens, what would you use the kit lens, mm for - walk-around?



Great review of lenses, I really appreciate it. I am considering getting an a and want to know if I should buy the body only, or get one with a kit lens. My impression is that kit lenses are not very good.



Kit lenses tend to be a little lower quality than primes, but are totally functional. You can definitely learn on either, the kit lens will be a bit more flexible for having some zoom range; a prime will be a bit sharper and better in low light, but will require you to be more creative in your positioning.



Neither is right nor wrong! I also purchased the Sony wide angle lense. Either of the zoom lenses we list here would work, with a bit of fiddling. The mm is good if you only want to carry a single lens with you everywhere, though is pretty big.



This article helped me understand the lens I need for my qx1. And the prime lenses recommended are incredible. Glad you liked it! True, but it helps many understand how to even begin with taking the best photos while understanding strengths and limitations of introductory lenses.



Thanks for the helpful summary of the reviews. I was wondering if you could answer 3 questions: Lastly, of the fish eye, you only mentioned the fisheye adaptor that goes with the sony 16 and 20mm.



Are there more options in this category? Are they just massively inferior? Maybe this will help explain. This is a lens simulator from Nikon. Set the button next to both body and lens to DX to match the sensor and lens configuration of the Sony.



Then you can adjust the focal length of the lens and see how much difference you can really spot. If you like the fisheye look, then go for it! Who am I to tell you what to stick on your walls?



I expect at least a person or two to benefit from my post today. Fitbit support has been horrendous. I regret buying from a non-refundable seller. Those statements are unrelated. Very very very disappointed that the screen has short timeout.



The app and software, everything has drawbacks. It counts tons of steps. More stressful while running or even RHR resting purposes. Green light during sleep. Same users, unique users, and this is only those of us who manage to make an account and voice it.



Horrible experience with the device and the devs. People seem to need me to repeat things, so: Oh, look, another reply on the thread. Hi tim Very bright and helpful article. I have an A with the standard kit.



I also have a twenty years old, perfect condition Nikkor 50 mm F1. Will it give good performance for portrait pics using an adapter? I think Metabones makes an adapter that should work. When you say E-Mount, does that mean all of these will work in full frame mode on the A7S?



All of these will work on the Sony A7 series in crop mode. Absolutely great article helped me a lot! Looking to acquire my first budget prime e-mount lense. I will go for the Sigma f2.



Having the kit lense mm already. Is there a reason to prefer 30mm against the wider 19mm? What that means is that it approximately matches the magnification of the human eye.



Aloha Tim, What a great article! I already have two lenses that are not Sony and are not e-mount. I have already ordered the Sigma f2. Is there some type of adaptor I can purchase so I can use both e-mount and non e-mount?



Wondering if new Pansonic will work on A? This would be so much lighter than Canon lens I use on 5d when my son plays soccer. Panasonic and Olympus lenses work together on a format called Micro Four Thirds, which has the benefit of smaller bodies and lenses, but the downside of a smaller sensor slightly lower image quality and some optical differences.



But an a with a is still pretty dang light and portable. I know price is a big difference, but technically which one is better? Tim, thank you so much for this article.



And the discussion here is very helpful too. Among the ones mentioned, which one is the best for taking videos? Is it the 35mm f1. Also, I have a GoPro to take wide angle photos and videos. In fact, back in the film camera days, it was common for many cameras to include a fast prime as their kit lens rather than a cheap zoom.



Although the a will drop in price when the new one comes out. Thanks for the great article. This is my first mirrorless. I am seeing this camera being sold everywhere with the kit lens and very often bundled with the lens as well.



My questio is am I better off buying one of these packages or going body only and grabbing a different lens altogether? I want something versatile. I love the bokeh effect so would love to be able to do that.



These lists are based on the assumption that you already have a kit lens. Dear Tim, I have sony and I love it. I have 2 lens, its kit lens and I want to buy a new lens but I hesitate to buy lens 35mm f1.



For filming, do you think which one is better? Depends what you want to do. The 35mm overall is more useful. Hey I just wanted to ask you for more recommendations in terms of wide-angle lenses?



And do you know whether the sigma 1. If you want to invest, the Sony mm lens is meant to be pretty great. What are you looking for? Nice Article but it could have better. I found latest list of Top 5 Fitness and Activity Trackers.



It has some top quality Fitness trackers in the market! Hi, am stuck for a decision I have a camera with kit lens and the sigma 30 mm 2. I am trying to choose between the samyang 12 mm to give me a wide angle option or sell my 2 current lens and get the Sony fe.



Am into travel, landscapes and sports photography, will I still be able to get sharp images with the 1 zoom lens or is it to much compromise? We still think the Sigma 19mm is a better option for most people.



My usual recommendation in that case is to either rent the lens for a few days, if you can, or at least look at the images people are taking with it on Flickr to get an idea of its capabilities https: I feel the Rokinon 85mm F1.



Manual focus, but with the A focus assist I absolutely love it. I shoot live music in mostly low light and I cannot get over the quality of the images. The image below was shot from about 50 feet from the subject.



I agree with the MF being a little daunting at first. Another amazing piece of glass and very amateur friendly. Great article… Come see me on twitter https: You are the man. Should i pick up a wider lens for this?



Would it make more sense to do one of those zooms that heads out wide? What are you recommendations? First up, yes definitely try and get a nice wideangle lens for taking with you!



The other question then is if you want a zoom lens or something similar for capturing a bird on the other side of a ravine. Thanks for the idea. The Rokinon is manual focus, but it still does aperture adjustments, right?



Is having zoom from 10 to 18 worth it? To clarify on the last part, did you mean just the Sony has the better optics, or all three of those last ones? Part of my decision was really if I should just buy one full range zoom like that instead of a wide angle.



Even if I had a super zoom like that, something like the Rokinon would offer me sharper pictures for landscapes and better low light performance, right? With the Rokinon, the aperture is manual too.



The has the advantage of being a bit more flexible thanks to the zoom. As for if the zoom is worth it? You can get a feel for what these mm amounts mean using this tool from Nikon http: As for the zooms, I think the mm has better optics than the other two, https: The Rokinon will def give you better sharpness and low light performance.



All in all, it sounds like for this trip it makes more sense to stay less bulky and as wide as possible. Manual focus on a super wide angle is a relative hassle. I wish the Rokinon, like old Nikkor MF lenses.



I think in general super wides can produce photos that feel a little gimmicky. It is good to have for interiors. I think you can buy the Rokinon 12mm and another A body if still for sale than the mm alone.



A is small enough that you can carry 2 bodies, That way you are more ready to shoot whatever subjects, and you minimize the risk of dust or dropping a lens. How does the compare IQ-wise with the Zeiss?



Seems quite larger physically. I have mixed feeling about the, considering its cost. Over the full range it holds its sharpness remarkably well. Hey Tim — I am getting ready to pull the trigger on the A in about a week….



Any hints on the updates? I am considering the SEL and … but feel like I am missing a good prime lens. I have been looking more like lusting at the 24mm and was surprised you picked the 35mm over it.



The sigma 30mm 1. Newbie just looking for direction… Should I buy the two zooms and be done? Nothing really seems to cover the range of the Is it for the reach? Do you want better sharpness?



If just one or the other, you might be better served by a more affordable option, like the or a fast prime. Hi Tim, any chance that updated article will still be coming out? Looking to take a dive on a prime for my new a and am excited to hear your thoughts.



Front element is really small. I wish it was f: Hi Tim, Any word on when the updated article will be published? I am relying greatly on your opinion as I am new to mirrorless camera photography.



Any feedback is greatly appreciated. Hopefully the new Sigma 30mm 1. Initial reports indicate it is a very strong performer for photos. As others, I am a novice photographer and in fact, this is my first camera.



I have two options regarding lenses mm and mm lens costco or mm lens kit lens — amazon. For a beginner which one do you suggest? Or should I dump the default ones and get something else?



The mm has powerzoom, so you can zoom using a dial on your camera, but it has worse image distortion. Today… I learn the pictures are actually a slideshow, and there multiple samples.



Relatively light and small with a great zoom range. Best of all… Super sharp! Sometimes it is super sharp — check out any Sony message board for the multitude of problems with it, like lousy quality control.



I prefer it to the Sony though. I am not happy with the IQ of the The focal length and size are great. Sharp only in the center. I have the A7 with the Zeiss f4 which is a way better lens.



Both lenses are a bit overpriced and I got them grey market or used like new. I made some tests. The sensor difference at ISO or between the A and A7 is not that great, but the difference between those 2 premium lenses is huge.



Too bad because the equiv is a way useful lens for travel than the i tried and returning the, sharp but too large, too heavy and often focus hunting — why did Sony make such a heavy superzoom instead of a that would be usable?



I get much crisper images with the that i feel i am missing out if i shoot a trip with the I have also the pancake. Only way I can shoot with primes is with 2 bodies. Stefano; nothing divides opinion like the Z!



Certainly the contrast is visibly better in virtually all shots. My copy is great but no compact walk-around lens is perfect — even with a Zeiss badge on. They are always a compomise. When you stop it down beyond f5.



If I want to pick out architectural or natural detail, 70mm f8 does an amazing job. If you want to do Macro, or close-up only the centre sharpness matters anyway. I never used the I have the A7 with the I find the a much better lens than the A lot sharper, produces crisper images.



They are both expensive lenses but at least the delivers for the price. While i find the sharp at the center but degrades quickly along the sides. I actually quite happy with the Sony, quite sharp and uniform.



I really hope Sony comes out with a better standard premium lens for the A series. Hmmmm… The Zeiss has been universally paned by reviewers while the Zeiss has been universally praised. You must have received a really great Zeiss and a really bad Zeiss I do not think so.



I had my lens checked and it is within the norm. Photos with the have a lot more pop and crispness. I have seen samples of the online, there is a muddy look that should not be in such an expensive lens.



It is sharp in the center but the sides become quickly unsharp. I am going to test it again on the A against an old Minolta on the A7. My bet is the old Minolta may be better in general.



Any thoughts on how that would work out? Thanks for the advice. I got the Surfboard SB privately from a third party on CL thinking I could have some security with having my own modem. Security with settings such as user names and passwords on my modem.



That sadly was not available to do on my modem. Is the cable company the only ones that can see the settings on my modem? Am I right in this assumption or not? Am I the only that worries about security with their modems?



Am I loosing sleep over nothing? Am I even allowed to change any settings on my modem? Is there any advantages in doing so? Have I asked too many questions? Hi, How did you mark the right infinity focus for the Rokinon?



Do you just let it stay at this infinity focus while shooting cityscapes and other architectural shots while walking in cities? How about group photos using this lens? I just marked it with tape.



So just focus on a faraway object with focus magnification manually and then put a tape on that marker? I am just getting started with photography and two friends who make their livings in photography have geared me towards the a or a I have decided on the a because I think I would rather have a good camera body with several lenses than a great body with 1 lens.



With that being said I am looking to narrow down my decision on my first two lens purchases. I am traveling to Yellowstone and I am highly interested in shooting both wildlife and landscapes while there.



Next, I probably would buy the less expensive Sigma 30mm F2. As stated I am extremely new to this, I welcome any and all advice and opinions. If i am completely wrong in this mindset feel free to correct me!



My thought is to own those 3 lenses before my trip but I would like to buy them in the order I listed so i can start using the camera immediately and getting some practice in! Thanks for your input!



I am happy with the It is small, sharp, IS works well. I had the old Sigma 30mm. I wish it were f2 instead of f2. But if you have the maybe i would get the 19mm instead or the In any case as a photojournalist i find a f 2.



Just got back from my second visit to Yellowstone, this time with a new Sony a I purchased at Costco. I found the mm very good for landscapes of course but the mm was somewhat lacking in reach compared to my Nikkor mm.



I will say that I barely used the D on this trip as the smaller footprint of the a is a huge advantage for travel. Is the mm lens they refer to above the exact same one that comes in some of the a bundles?



However, look at Flickr! Outstanding and very helpful review! Thanks for the hard work you put into this. I have saved this in Pocket and added several of the lenses to my Amazon wishlist.



I am a beginning photographer, with a Sony Nex 3. What are a couple of options for this? And thanks for the article! Any of the lenses mentioned in this guide will work with your camera!



I would also consider the Sony 28mm f2, cheaper than the 35mm, very sharp. Hello, thank you for the good article! I am new with a, I currently have kit lens and SEL50F18 due to its price and performance, and thinking to buy a new wide lens the kit lens have a poor performance in poor light environment or is it just my skill that poor, Im thinking about Rokinon 21mmF14 to represent both focal length of rokinon 12mmf2 and SEL35mmf18 anyone have a thought about it?



I will mostly use it to take photo of my family and landscape will do traveling soon with my fam. The 12mm is great for landscapes, but might be a bit much for family stuff—but the 35mm is a really handy lens for most situations.



If your subjects are staying relatively still e. It offers the most versatile focal length 35mm full frame equivalent of any prime lens. Heading to Yosemite and Tahoe in a few weeks. Need to pick up a better than kit lens for my a Should I go with the SEL35mmf18 or the Zeiss I know… big financial difference but I want to shoot landscape and I like the idea of zooming in as I do not know what to expect on the trail.



On another note… is the a better call and investment? I hear so much about these two lenses I am paralyzed with indecision!!! The debate between and has been a long running one—just scroll down and look at some of the other debate going on here!



Between the and the 35, those are pretty different lenses! The mm would be essentially a kit lens replacement, and would do everything your existing lens does, but much better.



The 35mm would be very good in lower light, though. The mm is also much bigger on a camera than the 35mm, which becomes an issue when hiking. Either lens will take very good photos.



The mm is arguably more suited to a variety of situations especially wide-angle landscapes, but the 35mm wins major points in low light, portability, and excels at that one focal length.



It almost cannot take a bad shot. Yes, it is a bit large to carry around, I am a cyclist and simply use my iphone 6 for rough and ready pix. But the with Zeiss optics cannot be beat in my opinion. For me it would be between the mm and the mm.



Hi, Chris, sorry to bug you again. Except for the size, are there any other differences between them? Thank you for your help. I ma pretty new in this. It can certainly be used to shoot a single subject, like a person, but typically you would want to use a less wide lens for that e.



You can probably find lots of photo examples on Flickr; just search for Rokinon 12mm and A or whatever camera body you will be using this on. The one thing I would say is that if you are that new to this, then buying a manual-only lens like the Rokinon with an immediate interest in astrophotography seems pretty ambitious for a new photographer.



You are right with your idea to use Flickr to see what a precise lens or camera could do. By groups or by specific search. Since its MF, will you get to hear the beep sound when turning the focusing ring?



For a nicer picture, i will try to adapt. Generally speaking, the option most people rely on is either focus peaking or zone focusing when using an MF lens. Seeking for your advise which would be the perfect lens for me as i need a sharp image quality built with OSS which ideal to for weddings events, and low light conditions.



I recently picked up the Rokinon 12mm. Besides trial and error, is there a proven method to locate the correct infinity distance marker? Then adjust the focus to a point where something at exactly 3 feet is in focus, and so is everything beyond that.



That should be your infinite focus. I have the sigma 30mm f2. My favorite of all of them is the 50mm 1. I love both the Sigma and the Sony Sigma is mounted by default as it is much smaller and easier to put in bag and carry, but I use the 50mm quite often.



I use the mm zoom sometimes, but IQ is not that great as with the 50mm or the Sigma 30mm. I am currently waiting for a set of E mount extension tubes, I hope they will be more usable for much less money than the Sony 30mm Macro.



You seem to have missed entirely that the Pro zooms from Olympus are totally weather sealed whilst the Panasonic upgraded offerings are not. This is a major advantage for those of us working under adverse weather conditions.



I would also like to add that I disagree that people are served well by purchasing the so called normal focal length lens i. Then they can marry that purchase with moderate telephoto such as the various 45mm offerings.



For the prime lens shooter this means they can handily handle a wide assortment of shooting issues, from environmental portraiture to indoor events, travel and the like.



If a zoom is required then the top notch olympus can do the work and beyond of those used by the prime shooter. This all of course depends on taste and preference. My opinions are based on a once former lifetime when I managed a couple of camera stores in the good old days and sold hundreds of cameras.



I also took my training as a photo technologist. The camera comes with a tiny flash and no hot shoe to add a better flash which is ok with the kit lens but a problem with the lens because of the shadow the lens casts when the flash is used.



Recently, after less than 2 years with the lens, I sent in the camera and lens to Sony because my images were no longer sharp. I was told the sensor might need to be recalibrated.



Really really great article! Sony is so expensive. For videos, you want to prefocus before you shoot, and then record the scene! As in, they intend to no longer support them, possibly including not allowing their service to work on them.



Apparently they have had too many issues with them. Mine has been great for a few years, FYI. Hello there, thank you for this great review. I have a quick and maybe stupid question but the answer of importance to me.



Many thanks in advance! Probably the most affordable only-prime-you-need ever on a mirrorless? Does the faster lens and cheaper price offset the image stabilization and smaller size of the Sony?



First a word of praise, amazing post and such a helpfull comment! I travel nearly full time and the camera and lenses need to be bought towards that purpose. Also I need them to be lightweight and functional prior to being the best of the best.



I was thinking of buying the Sony FE mm f3. What would you think of this setup for long term traveling? What do you think? Thank you inadvance for answering any of these questions and all the help you provide for novice photo enhousiast such as myself!!



Overall that sounds like a really good spread of lenses! A couple of thoughts: Maybe someone can help me. I am thinking of getting the Sony body and would like to have a 1 travel lense.



I spend a lot of time in the mountains and do as much skiing as possible. Is there a better Sigma lense or Tamron? In the past I had a 28 — Tamron lense for a film camera and loved it!



To the best of my knowledge, the only Sony mm lens is one for Sony SLT cameras like an a77 , not for mirrorless cameras. For more on the utter confusion that is Sony lens mount options, I recommend this piece http: Hi Tim, This is the Sony lense I was looking at http: This is the Tamron one http: The price range is very similar.



That mm lens will not work with your Sony a without a special adapter. These are the lenses that will work with your camera http: I looked at the Amazno link and then went and did a more through search in Sony to find out which one it was before opening your second link.



For the Tamron, we specifically address that in the piece. Hi there, your link to the Rokinon lens on Amazon is actually model for Olympus and Panasonic not Sony. James, and Christine Strullu-Derrien Vol.
