Originally posted by Wethphotography I just reread your initial post in which you stated your required focal range: 30-70mm. In that case, I would highly recommend the Tamron 28-75mm f2.8; it is an awesome lense and does very well at 2.8.
I've been think seriously about the Tamron 28-75, and may buy it, unless I find a lens that alco can be used as an allround lens, which in my case means that it should start at 17-18 mm. The Sigma 17-70 does that, but it doesn't give me 2.8 lens throughout the whole zoom range.
The lens I'm looking for probably doesn't exists.
