Rick:

I've never had a problem dripping sweat on the camera while it's resting in the keyhole while hiking in CO, probably due to the low humidity here. Years ago I had a Nikon -- I think it was an N70 before I had the keyhole and I would hold it in my hand while hiking. In the North Cascades, in much higher humidity, I had sweat drip down my arm, hand, then shutter finger and go into the gap between the camera and the button and 'bzzzt.' It shorted and quit. I took it to the Nikon repair guy in Miami (who fixed the Miami Herald's photographers' stuff) and he said throw it away -- and I did.

mt miller:

Did you get the "unnamed" item similar to the keyhole harness or the whole outfit? Looks like the keyhole-looking thing is about $79 -- more than the keyhole harness, but that "locking feature" in the video is a pretty cool thing, since gravity is (all) that keeps the camera in on the one I have.
