Sigma 18-35 f3.5-4.5 on FX
I want a lens for occasional wide angle shots on FX. I don't need more than adequate in terms of resolution, etc. and I've found a Sigma 18-35 f3.5-4.5 which has the added advantage of being light. It's cheap, but I'd like to know if anyone has any opinions on this lens before committing.
