Originally posted by Adam They're taking so long that I'm starting to question whether or not the lens will even be coming out, despite reading that it will.
My friends at Gentec, the Canadian Sigma distributor, have already done "mount replacement" on three new lenses for someone here in Ontario because they got tired of waiting. There's now a Pentax mount 18-35 f/1.8 and a 120-300 f/2.8 out there, and a 24-105 f/4 mount waiting. The last two aren't even supposed to be available for Pentax! The parts (including ROM chips) in Pentax mount must be available to do this, so my guess is these lenses are ready for production in Pentax mount. Naturally, no distributor is going to say "we're selling every Nikon and Canon mount lens you send us... can you stop and make some in Sony and Pentax?"
