Sigma 180mm F3.5 EX IF HSM Macro Lens for Canon-AF Camera

Rating:
Summary: Not great
Review: I feel that this lens seems a lot slower then my others. Since this is not a lens that I must use since I have a better lens at the same focal length I rarely use it. I don't recommend it but others might like it.

Summary: Better choices are available.
Review: Unless you need the extra distance afforded by the 180mm focal length of this lens (i.e. you want to work father away from your subject), your money would be much better spent on Canon's 100mm f2.8 USM macro lens. Canon's 100mm macro is also capable of 1:1 reproduction and offers better optics and build quality. More importantly, Canon's lens costs less than this Sigma lens. Save your pennies and work with a shorter focal length -- you won't regret it. This lens, while capable relative to the rest of Sigma's products, is not in danger of producing really impressive results.
