The Sigma APO 120-300mm f2.8 IF Lens for Nikon features a large aperture of f2.8 at the 300 millimeter focal length and is optimized for use with digital SLR cameras.
The latest in multi-layer lens coating technology and lens design reduce flare and ghosting, which is a common problem with digital cameras, and it also creates an optimum color balance through the entire zoom range. This lens is easy to hold and use. In addition, since the front of the lens does not rotate, a circular polarizing filter can be easily attached and used. High-speed focusing is possible when this lens is used with dedicated APO EX 1.4 x or 2x tele-converters.
