I’m selling my Sigma 10-20mm Wide Angle lens. It’s for Nikon’s DX format cameras, and it’s the last piece holding me back from going to a D700 (or it’s replacement, in the spring of 2011 – possibly March). I don’t do as much wide angle work as I need to in order to justify keeping it, and on a full frame camera body, it’s not going to be all that useful. That said, it’s a very good lens, nice for wide work as long as you keep it above f/8. Any faster than that and overall sharpness starts to slip away. Considering that I can handhold the lens at 1/30th of a second regardless, and I’ve got very unsteady hands, running at f/8 isn’t hard to do unless you’re shooting indoors at night.

So, I’m selling mine. I’m asking $400, and I’m going to include the $70 HOYA Pro1 UV[0] filter I have for it. This is a low-profile filter designed for wide-angle lenses, to avoid vignetting when shooting at 10mm.
