Sigma 30mm F2.8 EX DN Review by Tobias Giesen

I had been very much looking forward to
trying this lens, especially because I wanted to see how well Sigma would
implement the full MFT mount functionality. This is the first lens from a
manufacturer other than Olympus and
Panasonic to provide AF and full electronics
with the lens. I have received a regular retail copy of the lens
today (Feb 21, 2012) and I payed the full European price for it (199 EUR).
Although the focal length of 30mm seems to
have been originally chosen for Sigma's own fixed lens camera, I think it has
some merits on MFT also. In some cases, this focal length can be quite useful.
For example, for casual children portraits,
I have found the Panasonic 25mm to
be too wide, while the Olympus 45mm requires me to keep more distance than my
son will usually let me. With the new Sigma 30mm lens, I have been able to get some shots with extremely sharp
eyebrows,
something I never quite accomplished
with the Panasonic 25mm. Probably
my own fault, but I do like the 30mm focal length,
and F2.8 is more than enough
in many cases.
The lens feels good, and the AF motor is
quick and nearly silent. It is certainly faster and more silent than the
AF
is on the Panasonic 20mm F1.7 lens (which is still a must-have, while the
Sigma is not). During manual focusing,
you can hear the individual steps that the motor does though, when changing the
focus from infinity towards
closer subjects. The other direction is silent. So it's not as quiet as the best
Olympus or Panasonic lenses are.
The manual focusing ring is plastic and it feels similar to some Panasonic
lenses that don't have a rubber ring.
The manual focusing steps are very small so you can really get the focus where
you want it, even when shooting
at a short distance (the minimum is 30cm which is not exactly a short distance).
Due to the internal focusing, the lens is quite robust since there is no moving
element that can be touched from the outside.
