Lens kit bundles for Canon 400d collyParticipant October 8, 2007 at 6:05 pm Hey Guys, quick question: On Digital Rev there are two versions: Sigma 17-70mm F2.8-4.5 DC MACRO HSM ?325 and Sigma 17-70mm F2.8-4.5 DC MACRO DC ?241 What is the difference and is there any reason I would buy the more expensive one? Madra RuaParticipant October 8, 2007 at 8:07 pm The HSM version has a newer, better, faster motor. Unfortunatelly it is so far only available for Nikon mount :( Viewing 2 posts - 16 through 17 (of 17 total) ← 1 2 You must be logged in to reply to this topic.
