AF 20mm f/2.8D Nikkor Lens
Compact, ultra-wide-angle lens
The AF NIKKOR 20mm f/2.8D from Nikon is a wide-angle lens that is compatible with both full-frame (FX) and DX-format cameras, where it will offer an equivalent focal length of 30mm. The wide-angle perspective makes it ideal for architecture and landscape photography, or in any situation where a broad angle of view is required. This is benefitted by a fast maximum aperture of f/2.8 that make it suitable for working in low-light conditions and with shallow depth of field techniques.
The lens uses a Close-Range Correction (CRC) system to produce sharper images, even when focusing on subjects as close as 25cm. A Super Integrated Coating (SIC) further helps to reduce lens flare and ghosting for improved overall contrast and image quality.
Please note that this lens's autofocus function is compatible with Nikon DSLRs featuring a built-in autofocus motor. It will not support auto focusing when used with certain DSLRs that do not have an integrated focus motor.
