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.
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 lens is very suitable for taking pictures in nature
and it enables to use of natural light conditions or flash.
The greater working distance of this lens is very advantageous when taking
the picture of a flower among the branches or an insect. You do not shake
your subject when you want to take its precise details without blurring
by using a tripod. The narrow angle of view is a great aid for simplifying backgrounds and
shallow depth of field makes it easier to handle the composition. This
lens would have an equivalent field of view of a 178mm telephoto macro
lens on a digital SLR camera (when used with the SD10).
Depth of field of medium telephoto macro lenses is generally very shallow;
however, Sigma, Canon and Konica Minolta mounts of this lens have a minimum
aperture of F45 (or F32 for Nikon and Pentax mounts) for incredible depth
of field.
A screw-in hood is included, for convenient use of circular polarizing
filters. It is possible to attach an 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 whilst focusing manually.
