The AF-S NIKKOR 20mm f/1.8G ED from Nikon is a wide-angle lens that is compatible with both full frame FX and DX crop sensor cameras. The fast f/1.8 maximum aperture allows a shallow depth of field for selective focus use, as well as shooting in low-light situations.
The lens provides a 94° angle of view (30mm, 70° equivalent on DX-format cameras), and has a minimum focus distance of 7.8", allowing you to get close to your subject while isolating it from the background.
Two aspherical and two Extra-low Dispersion elements with Nano Crystal Coating reduce sagittal flare and chromatic aberration, producing sharp images throughout the frame. Nikon's Rear Focusing System eliminates change in physical length of the lens when focusing. A Silent Wave Motor provides quick, near-silent autofocusing. A soft pouch and lens hood are included.
