Crazy video... good to know it doesn't need to be coddled ;-)
I got the 7D after killing my XSi by taking it out in a driving "mist" storm on the Oregon coast (shutter blew up... cost $200 to fix). Decided it was time to upgrade to pro tools with some weather sealing.
I recently got a 70-200 f/4L IS... and after owning it for about 5 days I slung it out of my Lowepro backpack (thought it was zipped up) onto rocks. It came out working just fine. That lens is incredible by the way... definitely the best money I've spent so far on my photography hobby!
I've also killed my 17-55 f/2.8 IS in the last couple of months. It had something go loose inside and ultimately the zoom ring seized up on it. To replace it I'm getting a 16-35 f/2.8L that I'm hoping will be hardier.
Apparently I'm fairly hard on my photography gear!
