The lens is produced in Canon EF mount, Nikon F-mount, Pentax K mount, Sigma's own SA mount, and the Sony/Minolta AF Mount varieties, all have the same optical formula. Since the lens covers full-frame sensors and includes an ultrasonic autofocus motor, it is fully compatible with most DSLRs on which it can be mounted physically. Reviews have noted excellent sharpness [3] and an overall performance on par with manufacturers such as Nikon and Canon, despite its price being significantly less than comparable offerings by those companies.[2]
The Art series of Sigma lenses can be connected to Sigma's USB dock, allowing the lens firmware to be updated and focus micro-adjustments to be configured at four different focus distances.[4]
