Sigma 24mm f/1.8 EX DG ASP Macro - Nikon Fit

This Sigma 24mm f/1.8 EX DG Macro, Nikon Fit has a macro focusing capability (minimum focusing distance is 7.1" for a reproduction ratio of 1:2.7). The 9-bladed aperture diaphragm obtains beautiful, circular out of focus characteristics. It incorporates a floating focus system and uses two aspherical elements for Minimized distortion, spherical aberration and astigmatism. The lens front does not rotate during focusing, thus allowing the use of a "perfect hood" and the easy polarizing filters. Optical construction was created to Minimize light falloff (darkening of the image corners) at maximum aperture-a big benefit particularly for digital cameras.
