Just wondering, anybody who owns a 200 2.8L, mark 1 or 2...
How does it take a 1.4x teleconverter, or even a 2x for that matter? How much is the IQ affected? For the 1.4x, does the AF suffer?
I'm looking for a lens in that focal range that is able to be stretched a little bit (for wildlife), as funds are rather limited, what with me being a student and all. I don't need IS either so that's not an issue.
Thanks for the info. I went to your page and am impressed by the sharpness and quality of your wildlife shots. What did you use to take these, if you don't mind my asking?
