Description
The Sigma 105mm f/2.8 EX DG macro
lens delivers superb, distortion-free images throughout its broad focus
range, from infinity telephoto to lifesize (1:1) macro, as close
as 12.2" without accessories. Its non-rotating front lens group makes it
easier to work with polarizing filters. A focus limiter helps divide the
broad focus range into more manageable chunks.
The "focus-free" mechanical design allows
the lens to autofocus without any interference from the manual focus
ring, making it easy to hold the lens without affecting the speed or
normal operation of the autofocus function. Rugged mechanical
construction also makes it durable enough for even the heaviest use
required by professional photographers. An ideal lens for a wide variety
of applications from nature photography to portraiture.
The improved DG lens design for
this lens corrects for various aberrations. This macro lens is specially
coated to get the best color balance whilst cutting down on ghosting
caused by reflections from the digital image sensor. The lens provides
the utmost correction against lateral chromatic aberration which is a
serious problem for digital SLR cameras.
