Includes reviews for the new "DG" digital SLR version of the lens. The Sigma 105mm f/2.8 EX Macro delivers superb, distortion-free images throughout its broad focus range, from infinity telephoto to 1:1 (life-size) macro, as close as 12.3" without accessories. This new medium telephoto macro lens employs a new design concept for digital SLR cameras. Its new lens power layout produces an excellent optical performance and also reduces flare and ghost. This new lens is designed to reduce the influence of harmful light caused by reflections from the digital image sensor. Macro 105mm F2.8 EX DG allows greater working distance between the lens and subject. High contrast and excellent image quality are made possible in all shooting ranges. This macro lens is ideal for digital SLR cameras as well as film SLR cameras.
