The Sigma 50mm f/2.8 EX DG macro lens is optimized for Canon digital SLR cameras. The advanced lens design corrects various aberrations and is specially coated to get the best colour balance whilst cutting down on ghosting caused by reflections from the digital image sensor.
The lens also features a floating focusing system that enables the lens to photograph objects precisely in the entire focusing range. It has a close working distance and is very convenient for taking close-up pictures of inanimate objects.
A screw-in hood is included for convenient use of circular polarizing filters.
