Fast, quiet, generally accurate. I'm getting about the same AF accuracy with
the Siggy on my 30D that I get with Canon lenses on this body: which is to say
good, but not perfect. When it misses, it generally front-focuses a little, but I
think this is as much the body's fault as anything. This lens seems about as
accurate in AF as my EF 100 f/2.
The build quality is very nice on this Sigma. When focusing from minimum
distance out to long distance, it is smooth and pretty fast, with a really nice
quality feel to the focus motor. There is fairly heavy glass to move, and the
HSM is up to the task. When focusing over a smaller range, around 8 to 10 meters
out, you can sometimes feel a little clunk in the mechanism, as it is moving and
stopping very quickly.
Overall, the lens feels very much like a slightly larger Sigma 30/1.4
I think they have optimized this lens for bokeh and uniformity across the full frame.
Distortion is minimal. Straight lines look straight. No visible vignetting on 1.6x crop
body -- even wide open. Colors are fantastic.
It is still possible to get low contrast with the lens, when shot in dim, soft light,
but I think it's still better wide open than the EF 50/1.4 or the CZ 50/1.4 Planar.
