Here you go, now I did see some vignetting wide open against a bright sky but dialed up 2 mm and it vanished, both pictures are here, unprocessed and some other samples. I can still live with a 20-135mm or just crop it out for 4x6 prints anyway. I think the pics look pretty darn good right out of the camera, I was ready to sell my Rebel when I first experienced it with the Kit lens. The Sigma sure has a great range and a .5m (1.5ft) macro.
