The Nikon AF-S NIKKOR 58mm f/1.4G Lens 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 even 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, quiet
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.
