It also has a ÒflatÓ fieldÓ 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 donÕt 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. Capture them with the Sigma Macro 50mm F2.8 EX DG
