Product Description
Product 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.

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.
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.
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.
