This high performance medium telephoto macro lens is optimized for digital cameras. Sigma's macro 105mm F2.8 EX DG allows greater working distance between the lens and subject. The Super Multi Coating reduces flare and ghosting that tends to occur when using digital SLR cameras. A screw-in hood is included, for convenient use of circular polarizing filters. It is possible to attach a 77mm filter in front of the lens hood. This lens also incorporates a Dual Focus (DF) system that is designed to make the lens easy to hold during auto focusing. The large focus ring offers smooth and positive action while focusing manually.
