Wow! Canon Repair - New Jersey sure turned my equipment around fast. Thanks Canon. FYI - here's the scope on my equipment. The 100-400mm 4.5-5.6L IS required a new focus ring, & adjusted the focus with my 1D MII. (whatever that means?) The 1D MII, the connctorassy,(that's how they spelled it) 1394 USB was replaced, Updated firmware (althought it was already updated) adjusted exposure & focus with lens, cleaned C-mos to factory specs.
No to put it through it's paces.
If anyone has any comments, don't hold back. (I don't believe this is an OE problem)
*laughs* It would be too much effort to write "connector assembly" I guess... Hope it's improved after all that!
I had my 70-300 repaired by Canon, and it was indeed a pretty good turnaround for the lens (mine was a recall repair so they didn't really have much motivation to push it through quickly either).
