150mm F2.8 EX APO DG HSM Macro S AF
This Sigma Macro 150mm F2.8 EX DG HSM is a large aperture medium macro lens ideal shooting the smaller things in our world that exist 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. With HSM (Hyper-Sonic Motor) a quiet & high-speed auto focus is ensured. Two SLD (Special Low Dispersion) glass elements provide optimum color correction and sharpness throughout the entire range and Super Multi-layer coating reduces flare and ghosting. It is also compatible with Sigma APO Tele Converters.
Ideally suited for taking pictures insects or other small creatures, but it is also the perfect focal length for facial portraits rendering the best perspective of the human face. This greater distance also allows the photographer more flexibility in lighting the subject with natural light reflectors. So 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. Capture them with the Sigma Macro 150mm F2.8 EX DG
