A very good lens...small, sharp, well built, versatile
Oh, wow, this lens is so much better than the 16mm (SEL-16F28). I know because I used to have the 16mm but sold it after getting this one. The 20mm is much sharper, better built, with a nice and versatile field of view. It also takes the two adapters sold for the 16mm (the wide-angle which I had for the 16mm makes this 20mm a 15mm; and the fish-eye which I don't yet have but intend to buy). 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.

Very tiny lens for wider angle photography and more
This is a tiny and light pancake lens (even smaller than the 16-50mm kit lens!). The 2.8 aperture allows for some bokeh and decent low-light performance on the a5100 (you may need to use aperture priority mode to take advantage of this lens). I also own the Sigma 19mm 2.8 lens and I feel like I will use this lens more as part of a very compact and light-weight kit even though that lens is pretty small (a5100 + the Meike MK-35mm F/1.4 APS-C or Samyang 35mm f2.8 FE lens). I simply wish this lens was cheaper!

great snapshot lens
They say the best camera is the one that you have with you, so I bought this to make my a7 more portable and turn it into a snapshot and street camera. The a7 will detect the lens and use Crop Mode instead of Full Frame, which gives you a 30mm view that is great for all around use. The image quality is not fine art level but good for what it is, an affordable and portable lens. There is slight distortion and vignette sometimes, but Sony has a lens correction feature built into the camera that does a great job of fixing them if they bother you. Also the more you avoid the extreme high or low F stops the cleaner the image will be.

Super cute
Makes my Sony A6400 into a point-and-shoot size. It is super cute. This is my first lens upgrading from the kit lens. So far, I am happy with it, if only for its portability. I actually hated the way the kit lens needed to contract and retract when turning the camera on. Can’t comment on the image quality yet. But I can say that it is extremely quiet when taking photos and autofocus is decent. It is terrible in low light, but that’s okay for my purposes. I’ll use my iPhone in darker settings. Paid about $300 by ordering through Amazon warehouse. The first one I received was defective and broken, autofocus didn’t work (tested in Auto and Manual mode) and none of the manual settings (shutter speed, ISO, etc) could be changed in Manual mode. So be careful when ordering a used one. The second one I received is great though! Recommend this lens. So portable and compact.

Discrete APS-C Lens
Super discrete! Allows the a6400 to fit into a jacket pocket or small fanny pack without much issue. When shooting on the street, the camera and lens combo is very light, compact and unremarkable. Autofocus is a touch noisy, especially in video with continuous autofocus. My mic doesn't seem to pick up the noise thankfully. You're not going to use this lens for really fast moments since the autofocus can't keep up - at least on the a6400. Works well enough for casual, moderate pace street scenes or kids. Picture quality is decent center of frame, but off-center it is soft wide open. Stopped down it is mostly okay. Bokeh is not so smooth, but you do get blur for out-of-focus bits. I'd say use this lens at f4-8 and use interesting compositions instead of trying to isolate with bokeh. Take this lens with you on trips where you can sacrifice image quality for convenience.

Compact, sharp, solid build
I got this lil lens to carry around while traveling and doing street photography, it pairs perfectly with my a6700, and it fits on my coat pocket. I really like how you can add a filter directly to the lens or on the hood itself. It's pretty fast, autofocus is quick, it's got focus ring and just feels solid. I had been looking for a small pancake wide angle lens and tried a 14mm, 16mm, 18mm and finally this one. Its exactly what I was looking for, the only thing in wish is it would go down to f/1.8 or 2.0

I used this for my vacation to the UK and it was great for carting around - light weight and easy to store away. Great for street scapes and landscape vista shots. I didn't have too many occasions to use it in low light conditions but it worked fine in the British Museum, for example. Not a high end prime, but then again not priced like one either.
