DESC: A fast f/1.4 aperture makes this lens a standout for sports photography and photojournalism. With Nikon's typical attention to details, its aperture has extra blades, enabling the diaphragm shape to be a near-perfect circle. This ensures crisper images and more flattering highlights in the out-of-focus portion of the image. Close-Range-Correction (CRC) affords superb optical performance from infinity to the closest focusing range of 2.8'. Accepts 77mm filters; HN-31 lens hood.
