Took the 2nd try at a new Sigma 10-20mm 1:4-5.6 DC out for a quick walk today to get some test shots to compare to the previous one I had ordered.
The first one was soft on the left hand side and seemed to focus at about 3' even thou I was center-point focused at close to infinity. this one is working much much better. I had it cranked up to F/32 to get a long exposure in the sun, this was hand-held on my knee at 1/6sec.
Also tried out the new Photomatix 4 (I've tried 3.X but never liked it) and enjoyed the results here from a single shot RAW file.
