I just got my dRebel XT & 24-70MM EF L lens back from Canon last night. It was delivered to my office after I left yesterday so I didn't get a chance to get to it until this moringing.
First of all...it is fixed...yea
Repairs were at no cost to me..."Repaired: Mount Lock Pin. Re-adjusted to insure fine tuining." Camera was cleaned as well.
The camera and lens came back well packed with no movement in the box when I shook it.
I just tested it with a couple of photos and it works just fine. I mounted and unmounted the lens twice and the locking mechanism is smooth as silk.
I FEDEXed it to Canon's NYC Reapir Center on 27 DEC 2006 and I got it back on 8 JAN 2007 for a 13 day turnaround and this over the New Year Holiday weekend.
I an a very happy camper. Kudos to Canon's NYC Service Center
