-- Mark Roberts< who sells it for that little? B&H, not the price leader, but pretty decent, sells it for $799. i read the Luminous Landscape review and have much the same results to report for the Sigma 15-30 f3.5-4.5 zoom when used at 15mm. center good to very good, corners, average. i almost always shoot stopped full down to f22 with it. acceptable for the amount of times i use it. given my preference to shoot at 24mm with full frame 35 though, i expect to start using it a lot more when i get my hands on a Pentax DSLR.
