The Sigma AF 70-300mm f/4-5.6 DG macro telephoto zoom lens has excellent cost performance and is optimized for use with Canon digital SLR cameras. Capable of macro photography, this lens has a 1:2 maximum close-up magnification at the 300mm focal length.
It’s the ideal high performance lens for portraits, sports, nature and other types of photography that frequently use the telephoto range. The lens uses Special Low Dispersion glass for excellent correction of chromatic aberration.
This also corrects for fluctuation of aberration due to focusing. The new multi-layer lens coating reduces flare and ghosting and also creates an optimum colour balance. The minimum focusing distance is 1.5m at all zoom settings.
It also has a switch for changeover to macro photography at focal lengths between 200mm and 300mm with a maximum close-up magnification from 1:2.9 to 1:2.
