Sigma 70 - 300
I was in what passes for a camera shop here and saw a Sigma AF 70 - 300 lens for sale. I don't know the model number but it's the model that has a switch changing it fro zoom to macros in the 200 - 300 mm range. There are several similar lenses on Ebay. The lens was fairly cheap, about $250 Canadian. The question is, is it any good? Has anyone on here used it? Would it be sharper than my Canon 75 - 300 kit lens?
I'm about to buy something to expand my kit but haven't yet decided on what will give me the best bang for my buck. The lens in question is a possibility, so is a 1.4 teleconverter. I'm also thinking about a set of extension tubes. I'd like to be able to do macro but also want a longer reach with sharper pictures.
$ are limited so this may be my last equipment purchase this year so I want to spend wisely.
