Sigma Corporation is pleased to announce the launch of the new Macro 105mm F2.8 EX DG lens. This medium telephoto macro lens employs a new design concept for digital SLR cameras; its lens power layout produces an excellent optical performance. The new lens coating cuts down ghost. The DG lens is designed to reduce the influence of harmful light caused by reflections from the digital image sensor. Its outstanding optical performance provides the ultimate correction against lateral chromatic aberration and distortion. This lens boasts compact dimensions of f74mm (maximum diameter) and 95mm (overall length). It has a filter size of f58mm and, at just 450gms, is also extremely lightweight. The minimum focusing distance of 31.2cm (12.2in) is capable of macro photography with a maximum magnification of 1: 1. It is possible to enjoy photography from life-size close-up to infinity. Sigma, Canon and Konica Minolta mounts have a minimum aperture of F45 for incredible depth of field (or F32 for Nikon and Pentax mounts). This lens is equipped with a "Focus Limiter Switch" that limits the AF range so improving the speed and accuracy of auto focus. It 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 whilst focusing manually. A screw-in hood is included, for convenient use of circular polarizing filters. This telephoto macro lens has an equivalent field of view of 178mm on a digital SLR camera (when used with the SD10).
