Who here has used either the Tamron, the ProMaster, or the Sigma 70-300mm AF lens with macro for Canon cameras? At around $200, this is not at all a pricey lens, but it seems to pack some bang for the buck. I'd very much welcome input from those who are familiar with it, and also recommendations within the same price range, if you feel something else might serve better. The glass will be primarily used for nature and outdoor photography.
