Right now I own a Canon 70-200 f/4L non-IS. I'm interested in a faster telephoto lens but am not in a position to get a Canon 70-200mm f/2.8L either with or without IS.
Would you look to the Canon 200L or the Tamron 70-200mm f/2.8? Or would you consder both of those to be downgrades and I should wait until I can afford a 70-200 f/2.8L?
No need to go into prime vs. zoom. I shoot a variety of subjects mostly as a hobby, and I am comfortable going either way.
[Edit: I am talking about the cheaper f/2.8 200L, not the much more expensive f/2.]
