Excerpt: I bought my Nikon 20mm f/2.8 AIS lens for night time Astrophotography. When paired with a full body/grip Nikon D800 it's extremely light and easy to shoot with. Hand held shots are easier to perform without shaking. I never tire using this lens. What I like most is it's sharpness and warm colors.
Pros: Consistent Output, Durable, Easily Interchangeable, Fast / accurate auto-focus, Lightweight, Nice Bokeh, Rugged, Strong Construction
Excerpt: I could have bought a used 20mm for less, although even older versions of it are pricey. But I wanted the latest coating on the glass, and I wanted to once again see a new lens just as I could have bought 15 or 20 years ago. It seems they do still make them the way they used to. The lens is very well made and gorgeous. Focus is smooth as silk, and the aperture ring has excellent detent. The glass is just beautiful. And with all that, it is a sharp little thing.
Summary: I always stopped at 24mm when assembling a SLR kit. Anything wider was too specialized for regular use and good glass gets pricey wider than 24mm. Except for this lens. Amazing color, contrast and sharpness. Barrel distortion is expected, corrected with DxO software or Photoshop. For ease of use and a great price, this lens can't be beat. I'm a happy customer!
Excerpt: I bought the lens for my Df, when I was in holidays in NY. I wanted to have a wider lens (I own the 24 mm AF-D), for landscape and interior use. I also considered the 20 mm AIS, and the Voigtlander 20 mm AIS-P. But it was the only one which was available as a sample product, so I was able to try it at the store before buying it. I like very much the tiny size, the beautiful colors and sharp pictures I have with it on my Df.
Pros: Affordable, Durable, Fast / accurate auto-focus, Good, Lightweight
Excerpt: Compared with too many other lenses, including some from Nikon, it is reassuring to have a lens with no unintentional Carpentier/Schiempflug effect built-in courtesy of 'mechanical slop' & the 'looseness' dictated by AF mechanisms. This lens is smooth, solid, built to a tight tolerance, and a pleasure to use. I also have the matching 28 mm & the Voigtlander 40 mm - no AF, no slop, & smooth operation. B&H were also a pleasure to deal with.
