After some info on the Sigma 10-20mm F4 Wide angle lens. DPReview gives it a reasonable wrap, but not a glowing one.
After some actual results from some members whom actually have & use them.....good, bad or otherwise.
Any advice I can get before purchasing one would be great - i'm purchasing for my sister-in-law to give to her hubby.
I have a Tokina 11-16mm f2.8 & love it & all aspects of UWA Lenses..!
