Hi,
I have just purchased a Sigma 17-70mm F2.8-4 DC Macro OS HSM Lens for Canon Digital Camera, to put on my 7D - wonder if anyone out there has any tricks they have learned with this lens, I need to get up to speed with it quickly, getting married in 2 weeks and will need to hand it off to a friend to take the pictures. I doubt if there is anything too tricky, just thought I would use this new resource from Ugly....thanks for any tips you can give me!
Mike
