Sigma 70-300 4/5.6 Dg-mac F/eos W/hd Just got this from Adorama for $84.00 used. Its $160.00 new, so I think its worth a shot at such a small price. I know its not the fastest lense, but I'll be taking pictures outside only with it in sunny Georgia, so it should do fine. I'll get one with image stabilization later. I just thought I'd share my most recent, really inexpensive purchase with you. Can anyone here comment on how quickly Adorama ships? I just got the regular shipping and it stated 4-6 days....you think thats about accurate for Ny to Ga shipping? If anyone has this lense, give me your personal review with it. Ive read the reviews on the web, but would rather here from a member who has used it. Thanks guys!
