OK. If I had an unlimited source of money, I'd buy a Canon L. But....that's not the case. So....I'm looking at a couple other lenses.
Sigma 150-500mm f/5-6.3 DG OS HSM APO Autofocus Lens for Canon EOS
Tamron Zoom Telephoto SP AF 200-500mm f/5-6.3 Di LD IF Autofocus Lens for Canon EOS
Will be used for Wildlife photography (and yes I know that's obvious by the thread), but mainly birds.
Anybody used or have any input on either lens. I have a specific one I'm leaning toward, but would like some feedback from people on here.
