The AF-S NIKKOR 58mm f/1.4G Lens from Nikon is a fast prime lens designed to excel at its bright f/1.4 maximum aperture. Through the use of two aspherical elements, a Nano Crystal Coating, and Nikon's Super Integrated Coating this lens has virtually no coma flaring or light falloff. This allows it to be used in low-light situations by maintaining edge-to-edge sharpness and balanced lighting at all apertures.
The 58mm lens features an aperture range from f/1.4 to f/16 and a rounded 9-blade diaphragm for producing pleasing out-of-focus elements, or bokeh. It also features a Silent Wave Motor for quick, near-silent autofocusing and Manual/Auto mode for fast switching between auto and manual focus. Additionally, this lens has a 1.9' minimum focusing distance and a 72mm filter thread.
It uses Nikon's F mount for compatibility across Nikon's entire range of FX and DX-format DSLR cameras. Also, when used with DX-format cameras it provides a 35mm equivalent focal length of 87mm, ideal for portraits.
