Manufacturer Description
Lens-making is an art--Nikon artisans craft Nikkor optics from the finest materials, taking pride in adding their intellect and technique to bring the world's finest lenses to life. They push the leading edge of lens-making in their effort to provide the "glass" that makes the world's greatest pictures.

AF Nikkor lenses work with Nikon SLRs for optimal performance, even the very latest. The Nikon 20mm f2.8D AF Wide-Angle Nikkor is a compact ultra-wide-angle lens constructed with superb optical design for architecture, wedding and landscape photography. It features 94-degree (70-degree with Nikon DX format) picture coverage with edge-to-edge sharpness. The Close Range Correction (CRC) system provides high performance at both near and far focusing distances, for distortion-free pictures as close as 0.85 feet.

Nikon Super Integrated Coating ensures exceptional performance
To enhance the performance of its optical lens elements, Nikon employs an exclusive multilayer lens coating that helps reduce ghost and flare to a negligible level. Nikon Super Integrated Coating achieves a number of objectives, including minimized reflection in the wider wavelength range and superior color balance and reproduction. Nikon Super Integrated Coating is especially effective for lenses with a large number of elements, like our Zoom-Nikkors. Also, Nikon's multilayer coating process is tailored to the design of each particular lens. The number of coatings applied to each lens element is carefully calculated to match the lens type and glass used, and also to assure the uniform color balance that characterizes Nikkor lenses. This results in lenses that meet much higher standards than the rest of the industry.

Close-Range Correction system
The Close-Range Correction (CRC) system is one of Nikon's most important focusing innovations, for it provides superior picture quality at close focusing distances and increases the focusing range. With CRC, the lens elements are configured in a "floating element" design wherein each lens group moves independently to achieve focusing. This ensures superior lens performance even when shooting at close distances.

Distance information
D-type and G-type Nikkors relay subject-to-camera distance information to AF Nikon camera bodies. This then makes possible advances like 3D Matrix Metering and 3D Multi-Sensor Balanced Fill-Flash. Note: D-type and G-type Nikkors provide distance information to the following cameras: Auto exposure; F6, F5, F100, F90X, F80, F75, F70, F65, F60, F55, F50, Pronea S, Pronea 600i, D2 series, D1 series, D100 and D70s/D70. Flash control; F6, F5, F100, F90X, F80, F75, F70, D2 series, D1 series, D100, and D70s/D70 cameras.

Customer Reviews

Amazing lens
I use this lens with D80, specially for landscape photography. This is an excellent wide angle lens; sharp and fast.

Very Good 20mm lens from Nikon
This is an excellent lens for landscape photography, other travel photography, and perhaps even interior photography, if you need to cover a wide area. This 20mm Nikkor is a relatively old design, dating at least twenty-odd years, but it is still a capable performance with fine contrast and resolution. Without question, it is a fine lens for both digital and film photography. If I was still using Nikon equipment, I wouldn't hesitate adding this lens to my kit.

Competent performer
The Nikon AF20mm f2.8 was designed as a "pro" wideangle lens back in the days when 20mm in autofocus was as wide as you could get. Originally introduced in 1989 it was the AF equivalent of the manual focus design of 1984 and uses the same optical formula as the MF. The subsequent addition of the D chip has changed nothing else. In it's day an AF 20mm was pretty radical and it was only superceeded in 1993 by wider primes as the pros sought wider and wider views. For most amateurs however 20mm on film will get you into the "superwide" range without breaking the bank. For digital shooters, dealing with the 1.5 magnification factor in Nikon D-SLRs, it becomes effectively 30mm, which is still wide enough for most situations.
Optically it delivers typical Nikon high color saturation and contrast, with distortions well controlled for it's focal length. While it is reasonably free from flare I strongly recommend the optional HB-4 lenshood designed for it and polarizing will be dificult for film shooters due to vignetting caused by the thick polarizing filter mounts of a "standard" polarizer. Digital shooters should not have this problem because the camera's sensor is only using the central portion of the projected circle - inside the area of vignetting.
Mechanically it is all metal and well constructed with an nice "solid" feel to it for an AF lens but those of us who still miss the old manual focus "tanks" will find the undamped focusing ring a little too "loose" when manually focused. As part of a planned outfit, it can form the wide angle anchor for a travel kit standardized on 62mm filters. Add Nikon's 28-105AF 3.5-4.5 and 70-210AF 4.5-5.6 and you have a lightweight kit for either film or digital SLR's
