The Nikon AF-S 20mm f/1-8G ED Lens 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 inches, 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- {Key Features} - F Mount Lens/FX Format - Maximum Aperture: f/1-8 - Two Aspherical and Two ED Elements - Nano Crystal Coating - Rear Focusing System - Internal Focus, Silent Wave Motor - Soft Pouch, Lens Hood Included {Box Contents} - Soft Pouch - Front Lens Cap - Rear Lens Cap - Lens Hood{Product video}
