Hi all, any guys here using sigma17-50mm F2.8 EX DC? (canon mount)
i just bought one during xmas and i find it having problem during focusing (in AF mode) when in live view and video mode. It does focus but the focusing ring will produce noise and it doesnt rotate smoothly. i would like to check whether is this normal before i send mine to sigma for checking. thank you very much
