From the Manufacturer
E 20mm F2.8 Wide-Angle 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 elements
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.
Rear focusing elements
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.

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.Read more ›
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.Read more ›
$350 seems a little high, but $290 or less for a used one is a steal. After all, it does provide the most pocketable nex configuration currently available. It's not going to fit into your pants pocket, but it will easily fit into a small bag/backpack or jacket pocket. Which is great for anybody trying to make better use of their camera and carry it with them more often. You know what they say, "the best camera is the one you have with you."

So so. Mixed results, just doesn't seem very sharp. Probably more fun to buy two cheap lenses like a 16-19mm fisheye and a cheaper alternative lense of this format.Published 4 days ago by Amazon Customer
