This Sigma 50mm F2.8 EX DG is a standard macro lens that is ideal for shooting the small world around us that exists virtually unseen. A macro lens is one which will focus on a subject close enough to render it life-size on the image plane in your camera. It also has a flat field front lens element so that it can shoot images of flat objects such as artwork or postage stamps and be tack sharp all the way across the image. So you don’t miss the tiny insects, flowers of the world or the details in a stamp or coin collection or a piece of embroidery all of which are seldom noticed but offer a fascinating world if you look closely enough.
