Has anyone used this lens? (Tamron 200-500 mm 5-6.3 LD IF lens) If so, what did you think of it? I was saving for the Canon 100-400 but this might be reachable sooner. I just don't want to waste money on a bad lens and will just save longer if need be. Mostly for birding shots and some other wildlife.
thank you,
