In case anyone's interested, I own a NEX-6 and an A6000. I have most of the "reasonably priced" Sony E-mount lenses: the 20mm with the wide angle adapter; the 30mm Macro (a nice lens if you can get one for a good price), the 35mm prime (one of my favorite lenses for its field of view and its sharp, high-quality images); the 50mm prime (a nice lens, especially for portraits with good bokeh); the 16-50mm PZ kit lens (which I take along with the 20mm when I want to travel very light but still have a bit of a zoom on hand because it takes good, but not great, pictures as you can see clearly see once you've tried the primes); the 55-210 manual zoom (great range, nice and sharp shots, fairly bulky, but I got it for only $150 so can't complain) and the 18-105 PZ "G" lens (which is a superb carry-around lens if you don't mind its relative bulk--it's long and wide, but not too heavy). I've also tried the Sigma lenses (19 and 30mm) but thought, "These would be OK if they weren't so cheaply made (scratch easily) and so bulky and if they had OSS." So I returned them in spite of their low prices. I've also tried for a weekend, but decided not to buy, the Sony 10-18 and 16-70 zooms and the Zeiss Touit 32mm. These are built with high-quality materials and take great shots but they are way too expensive, in my opinion at least, for the relative increase in image quality over the much less expensive lenses.
I'm sure somebody out there will want to quote image tests and pixel peeping comparisons to debate my opinion about this 20mm lens and/or the pricy Zeiss lenses, but my thinking is simply that this "mirrorless" line of medium-format cameras doesn't really need lenses that cost so much. I admit there is a small market for those lenses; they are priced for folks who are willing to spend 2-3 times the money for "something a bit better" (that's how Sony makes back the investment in building lenses that relatively few people will buy). If you really want to step up, I suggest that you skip the APS-C line altogether and buy one of the newest full-frame "A7" camera bodies and any one of the pricey full-frame lenses available for it. With 4 times the money invested, you can see some better images (all else being equal). But switching from APS-C to full-frame means you're not in the same ballpark at all, to use a worn expression. I can say all this with confidence because photography is a hobby for me, not a profession. I'm not taking pictures for National Geographic (I'd love to imagine doing so with my A6000 and one of my pedestrian lenses, but I am not a delusional man). What I am is happy with two Sony APS-C cameras I own. I make use of, and accommodate for, their relative merits. The broad collection of E-mount lenses I have covers most every situation I am likely to get into as a hobbyist. Even better, I bought all my lenses for about 60 cents on the dollar (another hobby of mine is being a bargain hunter).
If you're the kind of photographer that I am, then you'll want to know that this SEL-20F28 lens is a very nice lens to have. I bought it as a "new but sold as refurb" here on Amazon for about 40% off its list. For that kind of money, it really shines as a small, versatile lens (i.e., close-up shots and landscape shots are both very good). It's smaller and faster and sharper than the kit zoom; it also costs much more than the kit zoom. I will add that my 18-105 "G" lens takes a noticeably better (sharper, better contrast, less aberrations) picture set at 20mm than this prime does, but then the zoom is only f4.0 (minimum through its range) whereas the prime is f2.8 and it's 1/10th the size. That's why I have both in my lens bag.
I hope this long ramble helps someone decide whether or not to buy this lens. If not, hey, reading it was free. Peace.


I own the SEL16f28, which I purchased with my first NEX camera, the 5n.I thought that lens was very limited in terms of quality, hence purchasing the SEL20.
I now have the NEX 7 and this lens was tested on it
I must say that it's completely different from the previous, sub standard 16 version. The photos are sharp throughout, and I never have to correct chromatic aberration or distortions like I did with the previous model.
Autofocus is fast and accurate, even in low lit situations. I tried this both at home and outside, and the results were quite good. Pretty versatile when it comes to video too, as I think that after the SEL35f18 (at triple the price), this is probably one of the best for video. The distance on this lens makes video seem more "real" than the others, as they would be too narrow. With this lens you have a more "open" type of perspective, especially if you couple it with the wide angle adapter from Sony too (VCL-ECU1). I can confirm this works for photos and there is no heavy vignetting in the corners, but there is some, which is easily corrected in post. For video it also works fine, and there is a very slight fish eye effect to it, nothing crazy. I actually quite like it.
Photos are vivid, well contrasted and look quite natural. I tend to do more street photography than anything else, and I'm quite happy with the results. From buildings to people, to alleyways and running photos in train stations... results have been good and i'm keeping this lens! I can't see any alliasing or heavy artifacts as of yet, but then again if you go nitpicking there will be something wrong with every lens...
I have also tried panoramic shooting and really like the results, although it's not really my thing.
If there would be something i'd point out as not so good it would be the focus ring, as when i'm using manual focus this is difficult to use, as the lens is so compact. But still usable,
I am looking forward to taking more photos with this little lens, it has now become a favourite and permanent resident in my camera bag, along with the wide angle adapter. It's a great all rounder, and you can carry it without the added bulk of a bigger lens.
It does come with a front and back lid, and a lens protection cap/light shade. And better yet, the price is down to nearly half price! I don't think anyone will have a reason to complain with this low price. This lens was originally above the

The short answer is yes. It's a beautifully compact bit of kit, it has limited scope for shallow depth shots at a max. aperture of 2.8, but I think the compromise is worth it. I have my 35mm 1.8 which I adore, but the 20mm is so small it literally would be stupid to not take it with you everywhere you take your camera!
I'm mainly a manual focus user, as I'm more into artistic photography than family snaps - with that said I've been to a party recently with this lens and I did use autofocus for that occasion, plus flash due to the indoor night-time environment, and I'm pleased to say it was generally very swift, only occasionally struggling when subjects were really close (0.5-1m). Build quality seems the same as the high quality 35mm lens, and looks really sleek and discreet on the camera. The lens hood is unusual but clever, as it adds less forward bulk, avoiding that 'I'M A PHOTOGRAPHER' look which you tend to get with regular 'petal' types. The manual focus ring is extremely narrow, which took some getting used to, but thankfully the grip is very effective so it's hard to slip enough that you can't correct yourself quickly. Manual focus is also a lot more sensitive than the 35mm counterpart by Sony, so again it takes some getting used to, but I think after a while it actually allows you to track targets coming toward/going away a little easier which can be very helpful. Pictures so far have been really hitting above what I was expecting for the money. Sharp at 2.8 and very sharp by 3.5, bokeh can be really good if you have decent distance in your isolation, and I think will be extremely useful focal length (equiv. full frame length = 30mm) for general use.
I've made some outstanding choices with the 20mm and the 35mm, mostly from reading reviews here. They've been a real cut above the kits lens in terms of quality and practicality, and this one is a total steal at 180 quid. If you can afford it, and you're into street/architecture/travel/portraits etc, get both of these lenses and in my opinion you've got yourself a quality, versatile, compact little kit.



I was hesitant to put a preorder into B&H when this lens was announced. Sony's previous wide angle prime, the 16mm was a poor lens. I borrowed a friend's and gave it back quickly. It just wasn't sharp, and surprisingly for such a short lens, it didn't focus quickly. There are no focus problems with the 20mm.
It was a relief to look at my first images from this new prime lens. They are are adequately sharp from f/4 and smaller apertures. At f/2.8 they are at least as sharp as the old 16mm was at any focal length. It's also nice to see Sony make a lens that is sharp in the corners. Except for the Zeiss 24mm, Sony's lenses tend to have great center sharpness but soft edges. My guess is that comes from too much focus on video lenses rather than still lenses. This lens is pretty sharp, at least at the apertures that I normally use 5.6-8. It's acceptable at 2.8 and pretty good at f/4. It's soft at f/16 but still usable. I'm satisfied.
One question is how this compares to the Sigma 19mm, which is a good lens. The two obvious differences are price and size. You can pick up an older model Sigma for $150 or less, which make it very attractive. The Sigma is very sharp in the center, from f/2.8 on, sharper than the Sony 20mm. However the Sony is definitely sharper at the edges.The Sony has some color fringing at the edges. The Sigma shows more flare when pointed toward the sun. Neither is a perfect lens.
The real question is whether or not the Sony 20mm is worth ~ $350. If you're just looking at price and image quality, that's tough compared to the Sigma. I just sold some old lenses so I had money burning a hole in my pocket. You can get an optically equivalent lens from Sigma for less than half the price, but the Sigma 19mm is twice as long and heavier, making the camera a bit much to put in a coat or vest pocket. It's also plastic and makes clunking noises (it's not a problem, some Sigma lenses just do that). The Sony 20 is metal with a nice finish, focuses faster and makes my 5n more or less the equivalent of the new Nikon Coolpix A, which sells for $1100. A new NEX 5r with the 20mm lens runs $900. Put in that light, the lens doesn't look quite as pricey. Okay the Nikon's lens is better but you're stuck with 28mm equivalent. The NEX has interchangeable lenses, which is why I'm sticking with it..

Thus Sony launched this the SEL20f28.
At only 13/16 inches (20.4mm) 2mm shorter than the SEL16F28.
It weighs in at 2.4 oz (69g), the housed in a quality metal exterior with a silk black finish.
Its packing three aspherical lens elements correcting distortions.
Image quality in corners has been dramatically improved compared to the 16mm f/2.8 lens, as it only has one aspherical lens surface.
The 20F28 is clear and bright enough for those indoor family photo's.
With a 20mm focal length (35mm equivalent 30mm) and a bright maximum aperture of f/2.8.
The lens hood is not like any other Ive used, this has a rectangular slot in it, but can be left on the lens as protection.
Another handy feature of the hood is that it will go over a slim filter on the lens or a filter can be on the hood, or both!
"I have a Hoya UV, polarizing filter on the hood" as its can be removed with the hood to fit the adapter.
Many people have also asked on on the net if the wide angle adapter (VCL-ECU1) fits this lens
and yes it dose and nicely to. OK you don't achieve the as wide angle as you would if you fit the adapter to the 16F28
but then again the barrel distortion inst as bad or pronounced ether.
I bough this from Amazon to,
See VCL-ECU1 [Sony Ultra Wide Converter for NEX SEL16F28 Lens ]
I haven't tried the lens with the fish eye adapter (fish eye inst my thing!) But i cannot see any reason why it wouldn't fit ether.
With the wide converter on gives you
SEL20F28 x VCL-ECU1
20mm x 0.75mm = 15mm (or 22.5mm equivalent on a 35mm).
This is plenty wide enough for scenery for me.



however, i like the range of the lens when i use it to take shot of my girlfriends coz i want the background of picture to tell more story about the pic.





The finer detail of lens construction is always slightly beyond my grasp (three aspheric lens elements) but the results were not. Using the 16mm pancake lens as a comparison point, the 20mm gave closer-to-life colour rendition with impressive saturation in stills - and with slightly less distortion to vertical and horizontal lines. This seemed to tie in with the blurb that it `reduces distortion and aberrations around the image periphery... with improved resolution and contrast'.
The lens is very compact and can easily be placed in a pocket when camera bag space is at a premium. It is supplied with rear and front lens caps as well as a lens hood. As with most other lenses in the NEX series, this one is shipped without a case, which is a little disappointing given the RRP and the fact that it is one of many interchangeable lenses compatible with the cameras.
The hood is pre-fitted to the lens on arrival and is clearly designed with ease of use in mind as it is so sleek that it never really needs to be removed unless you want to add a convertor - which means one less piece of loose equipment to carry around in your bag and one less thing to clip into place before shooting. The hood adds little to the size or weight of the lens and the cap fits securely whilst it remains in place.
The SEL20F28 is a great lens that produces good video and still images. I really like the way the lens hood has been integrated and my only (very minor) criticism is that it would have been handy to get a case as part of the package, particularly as the lens is so small it can easily be placed in a pocket. Results have been stunning, even at lower light levels. Sometimes a zoom can provide too much choice and particularly when you need to travel light, the SEL20F28 might be the perfect solution.







The only drawback is what is inherent to a 20mm lens - your shots will still be wide-angle even with a 1.5x crop factor. This is not ideal for portraits and there is some mild distortion. However, for traveling and use in tight indoor spaces, it has been an excellent choice.
I tend to favor prime lenses over zoom because of better apertures, size/weight, and my style of shooting. I just tend to compose better with a prime. However, if you're not used to using a prime lens or want to avoid wider angles, there are several other options available for NEX line. For those looking for a daily carry lens, this might just be the one.
