This lens provides the utmost correction against lateral chromatic aberration which is a serious problem for digital SLR cameras. The new MACRO 50mm F2.8 EX DG incorporates a "Floating Internal Focusing" (FIF) system which enables this lens to photograph objects precisely not only at life-size reproduction but also at infinity. The lens has a minimum focusing distance of 18.9cm (7.4") and is capable of true macro photography with a maximum magnification of 1:1. Experience the enjoyment of real life-size macro photography. This lens is equipped with a "Focus Limiter
Switch" that limits the autofocus range, allowing the camera to focus more quickly. This lens has a minimum aperture of F/45 (for Sigma, Canon and Konica Minolta mounts) which produces a tremendous depth of field. A screw-in hood is included, for convenient use of circular polarizing filters. It is also possible to attach a 72mm filter in front of the lens hood.
This macro lens has an equivalent field of view of 85mm on a digital SLR camera (when used with the SD-10).
