hi i see sigma has brought out a lens to rival the canon 17-55 f2.8 and the tamron 17-50 f2.8.
i've held off buying either as i'm not too convinced about the tamron and the canon is very expensive.
the sigma seems to be at a price midway between the others. being a sigma i'd hope it has a better image than the tamron.
anyone used one?
how's the IS?
picture quality?
focus?
ta!

I am also interested in this lense. Here is a link.

cheers ron.
it'd be interesting to read an opinion or review from someone who uses it primarily for video work.

I have one, bought it about 4 months ago. It's a great lens, really sharp with still photos, the OS is dead silent to the point where I thought it didn't work. The only issue is manual focus ring has very small tolerances, so you have to be careful pulling focus, but other than that it's my go-to lens when shooting video on my 7d.

cheers tyler. it seems you are one of the few using it.

The tamron is actually a pretty nice lens

The Tamron is a great lens. If you dismiss this lens simply because of what seems to be a silly prejudice, then you'll miss out on a great product!

I have the Tamron and it is phenomenal. I'm shooting interviews at NAB with it, in fact.

I own the Tamron as well and it's the main lens I use. Great lens, OS works well.
