Sigma Corporation is pleased to announce the launch of the new MACRO 50mm F2.8 EX
DG lens.
MACRO 50mm F2.8 EX DG incorporates the very latest optical technology and is an ideal
standard lens for digital SLR cameras.
The new advanced lens design corrects various aberrations. This macro lens is specially
coated to get the best color balance whilst cutting down ghost caused by reflections from
the digital image sensor. 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 φ72mm 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).
