I was thinking of the Canon 17-85 to replace my "kit lens", I do like the extra length over the, say 17-55. However looking through the many posts on that lens, there are, very much, mixed feelings on it.
My attention has been drawn to the Sigma 17-70, admittedly, not as long as the Canon, but still worth consideration.
Does anybody have any experience, or indeed any strong feelings, of comparison between these two lenses.
The Sigma is also approx 2/3's the price of the Canon, for me that would be a bonus, I'd happily pay the extra for the Canon if I thought it was worth it. (IS, USM)
Thanks for any comments
