Introduction


September 2007

Nikon have a long history when it comes to 20mm wide-angle lenses. It started back in 1959 with their Nikkor-O rangefinder 2.1cm f/4. In 1967 the first update was released as a 20mm f/3.5, over the years the lens went through different upgrades. The Nikkor 20mm f/2.8 AI-S reviewed here dates back to 1984, it has a 62mm filter thread and features Nikons CRC (close range correction) which maintains image quality at near-focusing distances. 20mm lenses have been a favorite by landscape photographers for decades.

Positives


  • DOF/IR markings.
  • Build quality.

Drawbacks


  • Price $599.95 USD, $80 USD more expensive than the AF version.
  • CA, the first sample tested had some CA on all apertures on the Nikon D200. Second sample on the D3 showed some CA un till f/4, you also have to factor in the built in CA removal in the D3, but overall the second sample was quite a bit better.
  • Filter size, 62mm.

Verdict


The Nikon 20mm is a ok lens, it just costs to much, and in my opinion it does not live up to it's price. Compared to the Nikon 17-35 AF-S, the 17-35 @ 20mm outperforms the 20mm AI-S by quite a bit. On the plus side, the contrast and the OOF is really nice on the Nikkor 20mm f/2.8 AI-S.

Update December 12, 2007:
On the Nikon D3 this lens does not perform up to it's price tag. Too much CA, especially for the price of this optic.In perfect shooting conditions this is not a huge problem tough. But I do expect more from lenses in this price range. There is quite a bit of softness wide open as well. As with the D200 the Nikon 17-35mm outperforms this old lens with ease. The vignetting in the pictures with the D3 turned out to be exaggerated from the lens-hood.
