Sigma 105mm F2.8 EX DG OS HSM Works for Canon 550D ?
I am a big fan of ur site, with recent visits gave me abundant knowledge over lenses and caners. I have decided to go for this lens but disappointed to see that Canon 550 seems to be non compatible. Can you double confirm is it compatible or not ? I need this lens for my cam, else i have to change my cam !!!
Please advice me any alternative choice. No compromise on picture sharpness. It should be the best, its my concern.
