## Overview

The Sony SEL-20F28 is a compact, lightweight 20mm prime lens designed for E-mount APS-C cameras, featuring a bright F2.8 aperture and advanced aspherical optics. It delivers sharp, high-contrast images with minimal distortion, excels in low-light conditions, and offers a smooth bokeh effect thanks to its circular aperture blades. Its pancake design ensures portability without sacrificing performance, making it ideal for professionals and enthusiasts seeking a versatile wide-angle lens.

## Description

20mm F2.8 Prime Lens Not only will the 20mm (30mm in 35mm full-frame format) focal length and F2.8 maximum aperture appeal to experienced photographers, but the outstanding resolution of this lens will satisfy their most stringent image quality requirements as well. Three aspheric elements help to achieve superb contrast and resolution right out to the image edges, while simultaneously enabling a compact 20.4 mm-thick pancake design that makes for a portable combination with compact E-mount cameras. When changing your aperture to defocus the background, the light sources appear blurred. This ‘bokeh’ effect of the blurred background can be enhanced with circular aperture blades used in this lens. Conventional aperture blades have flat sides creating unappealing polygonal shaped defocussed points of light. α lenses overcome this problem through a unique design that keeps the aperture almost perfectly circular from its wide-open setting to when it is closed by 2 stops. Smoother, more natural defocusing can be obtained as a result. Aspherical lens design dramatically reduces spherical aberration while also reducing lens size and weight. Spherical aberration is a slight misalignment of the light rays projected on the image plane. This is caused by differences in refraction at different points on conventional spherical lenses which degrade image quality in large-aperture lenses. Specially shaped “aspherical” elements near the diaphragm restore alignment of light rays at the image plane, maintaining high sharpness and contrast even at maximum aperture and can also be used at other points in the optical path to reduce distortion. Well-designed aspherical elements can reduce the total number of elements required in the lens, thus reducing overall size and weight. Advanced Aspherical (AA) elements are an evolved variant, featuring an extremely high thickness ratio between the center and periphery. AA elements are exceedingly difficult to produce, relying on the most advanced molding technology to consistently and precisely achieve the required shape and surface accuracy, resulting in significantly improved image accuracy and quality. Only the rear groups of the optical system move to focus the lens, which allows for speedy AF operation and a shorter minimum focusing distance. Since the front of the lens does not rotate, operability is improved when shooting with a polarizing filter attached. 2013 Sony Electronics All rights reserved.

Review: 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 desertcart 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.
Review: 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!

## Questions & Answers

**Q: Why did sony omit oss image stability on this lens? with oss the speed can be reduced on a kit lenses to accomplish 20mm @ f2.8.**
A: I think you may be misunderstanding the benefits of OSS on a wide-angle prime lens. The wider the angle, the less the effect of camera shake on the image. OSS (and other stabilizing hardware/software) are most beneficial for long and/or zoom lenses. So, in other words, adding the cost, size, weight and complexity of the OSS hardware to the 20mm lens is not needed and thus adding it would far outweigh any advantages. I've taken hundreds of pictures with my 20mm (and the two adapters which make its field of view even wider) in all kinds of lighting (bright to dim) and I've never had reason to worry about camera shake. There's a technical reason why which I'll try to explain below. I have to ask...do you own a Sony camera that uses E-mount lenses? Do you own this lens? Have you ever taken photos with it? And finally, why do you ask the question? Your comment that "with oss the speed can be reduced on a kit lenses to accomplish 20mm @ f2.8" really makes no sense at all. The 20mm is not a "kit lens" and reducing the shutter speed (longer exposure) does not "accomplish" an aperture of f2.8. The bigger the aperture, the more the shutter speed can be increased (for a shorter exposure to allow the same amount of light to reach the sensor). I'm pointing out all this information because I felt the need to illustrate that your original question, and BoJo's answer, are both misleading. I hope the time I've taken to make these comments is useful to you or someone else. The SEL-20F28 is a fine prime wide-angle lens and due to that wide angle, it doesn't need OSS. There was no "omission" of a feature due to cost; there was no need for the feature. Perhaps that's the simplest answer to your question.If you look at the full line of Sony E-mount lenses, you'll see that the OSS feature is not included in the two primes below 30mm (the SEL-20F2.8 and the macro lens SEL-30M35); above that prime range and in ALL zoom lenses (which have much longer reach and narrower field of view the OSS feature is included. For example, in the prime lenses, the SEL-50F18 and SEL-35F1.8 have OSS, All the zoom lenses (e.g., SEL-18105GPZ, the SEL-1650PZ the kit lens, the SEL-55-210, etc.) have OSS because the longer the lens (i.e.., the narrower the field of view and the more magnification, the more camera shake becomes an issue). The issue is whether a lens needs the OSS at its focal range, not whether Sony decided to save money (i.e., make the lens cost less to buy--which does not necessarily equate to saving money for the manufacturer). I hope this extra bit of technical explanation helps. By the way, I think the ideas in the answer you got from "BoJo" to your question are both true and misleading because they omit the issue of field of view and its effect on camera shake. In other words, the comments are not "educated" in the sense of understanding photographic concepts and technology. BoJo's comments all relate to cost, profit margins and referring to competing camera models/makes that incorporate an anti-shake feature into the camera bodies (perhaps like Sony's Alpha line that are not "mirrorless" such as the A58 and A77II). In the "mirrorless" line of Sony Alpha cameras (with the exception of the new, bigger Full Frame A7II line) there's no room for OSS hardware in the camera body (hence the addition of OSS to the lenses), There's really no need to "ask Sony" this question; you just need to know something about lens technology that applies to all lenses regardless of their manufacturer.BoJo remarks that "(in-camera stabilization is) one of the clever advantages that camera makers who incorporate OSS into their camera bodies." That's true (and why the FE A7II line now has in-camera OSS), but the issue of the necessary increase in size of the camera body was not mentioned by BoJo. As another example, the Nikon 1 line of mirrorless cameras (a really small line of cameras with a 1-inch sensor) also use in-lens stabilization (Nikon calls it "VR" for vibration reduction) for exactly the reason I've explained...adding stabilization to the camera body makes the body much bigger, more expensive and more complex. Good luck.

**Q: What's the equivalent focus length in APS-C frame?**
A: Sony NEX/alpha cameras are 1.5x crop factor so you multiply 20mm x 1.5 factor to get a 30mm full frame (35mm film) equivalent lens which is a medium wife angle lens. Good for general street photography.

**Q: How much flatter is this one vs the 16mm 2.8?**
A: As far as I can tell they are the same housing size. This one has upgraded optics compared to the 16mm.

**Q: Does it have Optical Stabilisation?**
A: If your question is about Image Stabilization. The lens does not have this feature.

### ⭐⭐⭐⭐⭐ Very tiny lens for wider angle photography and more
*by J***N on December 3, 2019*

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
*by S***U on December 27, 2020*

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.
