A few q's about the Sigma 30mm, eBay and Sigma sevice before I buy...

Apart from that the lens is crazy sharp in centre, and at f8 the borders/edges are very good - more than acceptable for landscapes. Photozone shows weak resolution, but perhaps the lens contrast gives the impression its sharper in the corners?
Bokeh is crazy smooth. Build quality is very good, and I'm glad the sigma got rid of the rubbery finish on the lens (except focus ring). The lens is suprisingly smaller than the pictures of it have you believe (at least to me anyway

It's not HSM on Pentax is it?
It's not unfortunately

the lens also looks like this: http://www.pentaxforums.com/userreviews/data/73/Sigma-30mm-F1_4.jpg
(it doesnt have the 'window' that the nikon and canon versions do.)

If I have to do any AF adjustments, I might just send in to sigma as I heard they do adjustments free, and also people who have had their lens and camera calibrated by sigma are very positive.
