Sigma 257-107 Lens

The Sigma 105mm f/2.8 EX DG macro lens delivers superb, distortion-free images throughout its broad focus range, from infinity telephoto to life-size macro, as close as 12.2" without accessories. Its non-rotating front lens group makes it easier to work with polarizing filters. A focus limiter helps divide the broad focus range into more manageable chunks. The focus-free mechanical design allows the lens to autofocus without any interference from the manual focus ring, making it easy to hold the lens without affecting the speed or normal operation of the autofocus function.
