Anyone try using the new 70-200f/2.8 IS II with an extender and like the image quality. If you can please post some pics. I looked through the lens archive and didn't see any.

Seems there is some info there. I know for sure the 2x TC will degrade IQ, the 1.4X from what I have read most are happy with on lenses like you suggest using. I would not consider the 2x TC however. Canon 5D Mark II & 50D with 17-40, 24-105, 100-400, 50 f/1.4, 100 f/2.8 macro, and 1.4TC

They are handheld without flash at 280mm wide open (f/4). I have included crops 100%. First at 1/125s.  HOSTED PHOTO please log in to view hosted photos in full size.

The 70-200/II is equally sharp throughout the range so the difference in nominal focal lengths should be of no consequence. Without the extender it's f/2.8 and with the extender f/4.0   Now for the 7D 100% crops, first without then with extender:   In short, 1.6 crop + 1.4TC ruins the IQ beyond what I find acceptable. Not to mention that the otherwise magnificent AF lags seriously when the TC is used. So I rarely use it. Finally, the 5DII, 200mm, without extender, 100% crop:  Luka C.D| My photos

I know I used to have those. Sent it to Canon and the difference was like night and day. The 1.4x TC should not degrade the IQ by that much or slow down the AF to a point where it's unusable. It's certainly a possibility but I wouldn't bet on it. I've seen samples from other users with 7Ds and 1DMkIVs and the results are similar. As for AF - it doesn't become unusable - it just degrades heavily. Basically 7D + 70-200/II + TC AF is the equal of 5DII + 70-200/II AF. It's not impossible to use, just annoyingly slow when you are used to a very fast and responsive AF. Luka C.D| My photos

Heres an example @ 400mm, f 5.6 (wide open) ISO125, 1/320, IS on, 5D MkII Ah, but that's a 5DII. Different story altogether. For reference a very similar goose to yours but without TC:  100% crop:   100% crop:  Luka C.D| My photos
