  • New and most effective coating used for minimizing flare and ghost.

  • The use of aspherical lens reduces various aberrations and improves optical performance.

Sigma Corporation is pleased to announce the launch of the new 28-105 F2.8-4 DG lens. This large aperture standard zoom lens provides superior performance both for Digital SLR Cameras and 35mm Film SLR Cameras. This standard zoom lens covers frequently used focal lengths from 28mm to 105mm and allows a large aperture of F2.8 at the 28mm focal length.

It is very convenient for a wide range of applications including snap shots, indoor photography. The new multi layer lens coating and lens design reduce flare and ghost, which is a common problem with digital cameras, and also creates an optimum color balance throughout the entire zoom range.

The use of aspherical lens reduces various aberrations throughout the entire zoom range and improves optical performance.

This lens has minimum focusing distance of 50cm (19.7 inches) throughout the entire zoom range and it has also maximum magnification of 1:5.5. Because the front of the lens does not rotate, circular polarizing filters and a petal-type hood can easily be used.
