Hello to all,
I been waiting for a long time to have it. Now, time has come.
I feel a bit unease to say it but, on my 5D mk II or 50D, I find it disappointing (sharpness, AF precision, IS efficiency), for various outdoor work (sport, etc.)
I get much better pics with the 17-40 or 100 macro IS (ok, it's a prime).
70-200 is as good as my 24-105 (which is ...so, so), but not much.
I send it back to Canon for control, and wait. But ...
Do someone had same impressions with this first class lens, or is there a special way to use it ??
Thanks for your impressions.
