Interesting thread. I just got my 70-200 VRII back from El Segundo for warranty repair of a sticky/slow aperture. I re-installed the RRS foot this morning and what with it having been about 1½ years since I originally installed it, I took a few seconds to ponder why there's a trigger latch and a locking knob. Seemed redundant. When I get home I'm going to make sure that knob is tight!
In all Jim, it was an expensive mistake, but given the value of the equipment involved, I'd say you got off pretty light. Glad to hear you're back up and running.
Once my tripod slipped on some rocks and sent D300 + 16-85 into the Tuolumne River. What a horrible feeling that was. I pulled it out and pulled the battery immediately. It took a couple weeks for the D300 to dry out, and other than a dirty looking viewfinder it seemed no worse for wear. The 16-85 was disassembled/cleaned/repaired by El Segundo for a whopping $65 (!) and came back like new, and left me only needing to replace the cracked lens hood and crished C-PL to be back to golden. Although I always thought the water in the D300 might be a ticking time-bomb, that whole rig was stolen during a house break-in about a year later but now some idiot has a camera that was in the bottom of the river. I got an insurance payout and replaced with D300s & Sigma 17-50 f/2.8 OS HSM, back to golden again!
Edited to add... I just remembered seeing this. Jim, you might want to take a look at this product from RRS, for $28 maybe some explanation and future peace of mind:
"Nikon’s extremely popular 70-200mm lens has one weakness: its thin aluminum plate mount on the lens collar. This is where the removable lens collar foot slides onto the collar. It doesn’t take a lot of tripod use before normal torque causes this thin plate to become deformed. Ever noticed that your foot seems loose, even though that knob is locked down? Check the condition of the plate mount on your lens collar, then order our LCF-10P."
