I am hoping to upgrade my kit 18-55 lens that came with my T2i in the not to distant future.
I have been going round and round in my head about which lens to get. Do I want a bit more reach or better light across the whole zoom range.
What I came to for a conclusion is that either of those scenerios would be benificial over the kit lens so now I have narrowed it to 2 lenses that are "somewhat" in my budget range.
The Canon 15-85
The Sigma 17-50 F2.8
Now to my question. Since I have decided that both increased reach or increased light would be a step up for me I am going to make my decision based on Image quality from the lenses regardless of the fact that they do different things.
So I was hoping people could tell me their good (and bad) experiences with either of these lenses and which they think is the better lens.
To be honest I am leaning toward the Canon as I have heard lots of stories about "needing to get a good copy" on the Sigma. Also as I want this as a walk around lens and actually have a canon 35mm f2 for low light and portraits.
Thanks for any input anyone can give
