Sigma Zoom 28-105 2.8-4 Aspherical IF Af

SIGMA ZOOM 28-105mm D 1: 2.8-4 Aspherical is a versatile lens for full frame cameras. This review presents a model for Nikon cameras, but the lens was also produced for Sigma, Minolta, Pentax and Canon mounts. In 2005, the lens was upgraded to a 'DG' model - SIGMA ZOOM 28-105mm 1: 2.8-4DG. The prefix that appears in the name of the lensDG'means that the lens has been redesigned specifically for use on DSLR cameras, while the review version was originally intended for film cameras. The new version can be quickly distinguished from the old by the signature Sigma velvet finish and the lack of 'Aspherical' lettering. Also, there is informationthat manual focus lens versions were released for Nikon AI, Pentax K, but, unfortunately, I could not find any photos of such a modification on the network.
