I sent a Mark 2 into Canon Irvine for a new shutter after the old one failed at 400,000 actuations or so. They shipped it back free the next day with a new shutter and new LCD (old one had a scratch). Total cost? Zero!

That's pretty sweet! Mine failed after 30K, and they forgot I was a CPS member and it took 6 weeks!

Hey I'm glad for you Greg! You sound like you have calmed down a bit. 67 bucks=bargainX10

Scott, sounds terrible. I emailed Canon Irvine first and they sent me some files to print as labels on the ship box that made a big thing out of being a CPS member. Maybe that was my luck charm.

I did get screwed once. Paid $2000 to fix a trashed body and they returned it still trashed. Did get it right the second go round.

You sure it's the rotation stop ball thingie, and not the actual bearings the collar rotates on? Those bearings come loose/off and you end up with spanner in works. http://www.naturescapes.net/phpBB3/view ... 3#p1691935
I think the bearings need to be loctiteed in place, but haven't braved it on mine yet.
Agree, for this to happen on expensive pro kit you have to say the collar is crap.

Neil - I was unaware of a change in design but after reading the above thread it makes sense. I will keep you posted. I hope to have the lens back tomorrow....heading south on Monday!

FYI- if you feel your Canon 70-200 has some loose play in the center you can peel back the rubber focusing and zoom ring bands and make sure the set screws are tight. Both E.J. and I, as well as others had the older version come apart. Hope the new one is better designed.

BTW- I did have an older Nikon zoom do the same, wink.

Lens is back in my hands - guess what it was stuck for a second when I took it out of the case but I think it is better now. At least I can move it. It was a fast repair that is for sure - still the design is poor but it's at least fixed for now. Can't wait till the newer versions come out and hope that the collar is better.

Screws loose? There are all kinds of screws that come loose on my lenses, teleconvertors etc. Happens all the time. The 1.4 tele did it again when in CR - gotta get some of that loctite again..grrrr

Extreme vibration for extended periods of time often results in screws coming loose. This vibration is always present with air travel and can wreak havoc on delicate photo gear.

One solution is to use Pelican hard sided luggage where one opens a specific hole in the interior foam and compresses the gear. This damps the vibration considerably. The con is this luggage is heavy and attracts attention.

Some use clear nail polish OVER small screws to keep them in place. Locktite in the threads can be a bit much if something needs to be taken apart later.

Electronic damage is another airline vibration problem. My friend, Paul Renner, runs 4 or so trips to Africa a year from the US. He has had way too many cameras fail in transit, EXCEPT for the top pro bodies. Apprently, durability is something the $5000 buys.
