Sigma 105mm f/2.8 EX DG
|
High
performance medium telephoto macro lens optimized for
digital cameras
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.

Reduces flare and ghost
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.
An easy to use 105mm medium telephoto lens
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).
Minimum aperture of F45
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.
Screw-in lens hood
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.
Dual Focus (DF) system
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.

Dr. Andrew Stevens - British Journal of Photography -
January 2005
'The lenses are stylishly presented in a black satin finish
and incorporate a manual / auto focus, along with focus
range limiting switches. ...Both lenses have a maximum
aperture of f/2.8 and, in the case of Sigma, Canon and
Konica Minolta mounts, there is an unusually small minimum
aperture of f/45 (f/32 for Nikon and Pentax). Although
diffraction reduces resolution at such settings - f/45
becomes an effective f/90 at 1x magnification, approaching
pinhole dimensions - this can provide beautiful effects with
some shots and Sigma is to be applauded for providing this
option. Both lenses produced excellent results, with fine
detail and smooth tone gradation over a range of
magnifications.'

Digital Camera - June 2006
‘The manual focus setting is firm enough for confidence and
provides accurate control in close-up and telephoto use.’
‘The Sigma in particular produced razor-sharp images at
close quarters, and held its performance admirably
throughout all the imaging tests we subjected it to, with
constantly good detail and strong contrast at the telephoto
setting.’

Ephotozine - May 2006
‘A good lens made better. The improvement in contrast and
extra control of flare and ghosting provided by the DG
coating are, in themselves, worth the upgrade. Improvements
have also been made to the hood along with a reduction,
albeit slight, in the AF noise. Optical quality cannot
really be faulted and with the edges performing as well as
the centre on a cropped camera you can expect good edge
performance on a full frame body too.’ |

|
 |
What Digital Camera - August 2006
‘The lens has a dual focus function: the focus ring snaps
backward and forward between manual and autofocus, making
critical adjustments easy and quickly. If you use AF, the
lens has a limiting switch so focus stays within a narrow
range. Where the Sigma 105mm optic performs well is in its
control of chromatic aberration, which remained
insignificant throughout the aperture test both in the
centre of the frame and at the corners.’ |
| |
|
 |
Which Digital Camera - September 2006
‘The manual focus ring is disengaged by a very positive
pull/click backwards, allowing the AF to operate without
turning the manual ring.’ ‘A superb lens that’s excellent
value for what you get. This lens will deliver to even the
most critical users.’ |
| |
|
 |
Photography Monthly - September 2006
‘Optically there’s nothing to moan about - this is one fine
lens.’ ‘It’s a real cracker and its showing even at f/45 is
impressive. Top value, too, and with the advantages that
it’s available in most fittings.’ |
| |

 |
Practical Photography - March 2007
‘The Sigma 105mm has proved to be a popular lens, its
combination of ideal focal length and fair price winning
many photographers over. Of course, it’s 105mm effectively
becomes a 157.5mm when coupled with most D-SLRs and this can
be helpful when photographing insects that are spooked if
you get too close.’ |

Digital SLR User - July 2007
‘In terms of images produced there is very little to
distinguish the Sigma from the equivalent branded lenses.
Lens flare is low and there is good contrast across a range
of shooting conditions.’ ‘An interesting feature of the lens
(appearing in all mounts apart from Nikon and Pentax) is a
minimum aperture of f/45, which of course produces a decent
depth of field even when working close-up.’ |

Amateur Photographer - 25th August 2007
‘The Sigma 105mm f/2.8 performed excellently. In the
important parameter of drawing accuracy, which is essential
for a true close-up lens, it was particularly precise. At
1:1 it just had the edge of the regal Nikkor.’ It is a very
modern lens with a crisp definition and contrast on the high
side that contemporary trends favour.' |
