Description:

Sigma's 70-300mm f4-f5.6 APO macro super lens has a compact apochromatic telezoom lens that incorporates two special low-dispersion glass elements in the front lens group with one special low-dispersion glass element in the rear lens group. The arrangement of the optics serves to minimize the chromatic aberration that can occur.

This telemacro zoom lens can achieve a magnification ratio of 1:2 (one half life-size) for macro and telephotography images at its 300mm focal length. As an accessory, you can add a 58mm achromatic close-up lens (not included), and get even closer focusing and reproduction ratios of 1:1 (life size) and still maintain excellent optical quality. The optical materials are made from lead-free and arsenic-free ecological glass. This model is dedicated to Canon AF SLR cameras.
