Hi,
I am thinking of buying the Sigma 10-20mm f4-5.6 Canon fit. But I have heard/read a lot of people having problems with them, and on some occasions actually having 2 or 3 lenses before getting a good one.
So how do you know if you have a good one or not? Is there something specific to look out for? Are the problems all the same. Any help/info would be great.
Thank you.
Neil
