I just don't know *how* well sealed the lens is, but I do know that the repairs consisted of replacing the "track" that adjusts the focus with relation to the zoom barrel (it had broken somehow?) and a lot of the ancilliary parts. I would think that the air pressure differential wouldn't be that much - after all, I've taken other lenses overseas with nary a problem, and have done aerial photography at up to about 9000' (not counting shooting out of a pressurized jet) with no ill effects... true, it was film gear, not this new fangled stuff, but nonetheless, it shouldn't make a dif, I'd think.

Since there IS no warranty on the 16-85 (NEVER again...) I may just try to find a manual for it to do my own disassembly (yeah, guess I am just about crazy)... order the parts and re-assemble. But I want to know WHY it disintegrated so KNOW the body is not to blame... and if it is, so I can get it fixed. Ergo my latest question if the body might be what's causing this, er, now these lenses to discombouboulate themselves...

More 2b later...
