Sigma 70-300mm f/4-5.6 DG Macro (Canon AF)

High performance lens optimized for use with digital SLR cameras

Capable of macro photography, this lens has a 1:2 maximum close-up magnification at the 300 mm focal length. It's the ideal lens for portraits, sports photography, nature photography, and other types of photography that frequently use the telephoto range. 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.SLD (Special Low Dispersion) glass in this lens provides excellent correction of chromatic aberration.

Coating reduces Ghost and Flare
The multi-layer lens coating and lens design reduce flare and ghost, which is a common problem with digital cameras and also creates an optimum colour balance through the entire zoom range.

SLD (Special Low Dispersion) glass
SLD (Special Low Dispersion) glass is used in this lens for correction of chromatic aberration. This also corrects for fluctuation of aberration due to focusing. High optical performance is demonstrated throughout the entire zoom range.

Macro shooting with maximum magnification 1:2
This lens is capable of macro photography with a 1:2 maximum close-up magnification at the 300mm focal length. The minimum focusing distance is 1.5 m at all zoom settings.
