While I'll grant that I've only used one Sigma AF lens that was not terrible and a number that were atrocious, the 24mm performed very well for me on film for around six years. Aside from the flare.
Ever seen the Sigma AF 28-105 f2.8-4? At 28mm it had what we liked to call Gumby Distortion. -Aaron -----Original Message----- From: Godfrey DiGiorgi <[EMAIL PROTECTED]> Subj: Re: Pentax lens revelation for *istDL newbie Date: Tue Apr 25, 2006 8:52 pm Size: 768 bytes To: [email protected] On Apr 25, 2006, at 5:12 PM, Aaron Reynolds wrote: > I initially thought I was seeing limitations of the format or the > chip or whatever, so I shot at infinity with my 50mm f1.4 and my A* > 200mm f2.8, both of which were razor sharp.

It's a Sigma lens and therefore, in my utterly biased and not particularly humble opinion, just a piece of junk that looks like a lens. Worrying about infinity focus calibration is going overboard. The fact that it works at all is the miracle of Sigma lens engineering. ];-) - obligatory smiley Godfrey
