Not 35mm, but my Pentax 67. I had my first tripod oopsie with it, dinged a lens filter ring up and popped the meter readout loose in the viewfinder but it kept on ticking through the storm I was shooting in. Had it in a Nanuk case (like a Pelican), tripped on a watershoe lace and not dropped, but THREW it six feet off a dam retaining wall down onto rocks. I'm talking serious swing, a wound-up throw straight into the ground. Didn't even faze it.

Doesn't match some of the stories here, but it's impressed me so far.
