I've noticed that I seem considerably more cavalier about placing my camera gear very close to action, or in otherwise risky situations, than many other photogs. I started by burning out a Vivitar 383 flash. Nothing fancy, I just pushed it too hard covering a street dance party.
A fire performer's lit prop clocked the bottom of my 20mm f2.8 USM prime's lens hood and left a little fuel behind. It burned for a few seconds (long enough to partially melt the hood) before I wondered why my shots suddenly had an orange glow in the lower right. Still my favorite battle scar.
Later, I burned out a 580EX II flash when I loaded it and its auxiliary pack with lithium batteries to shoot indoor derby in a much brighter arena than I'm used to. Didn't think hard enough about the increased power draw from trying to compete with ambient light, and after 10 minutes of intermittent burst shooting, I needed a $200 repair.
While shooting skiing video, a few inevitable falls with my home-brewed GlideCam cracked my video light's shoe mount and twisted the camera off the stabilizer. It's fine, but the set screw I used to keep the camera from rotating off the tripod threads tore a lovely gouge in the bottom, right through the serial number.
Shooting candids of people running for cover during a sudden downpour at Pig & Whiskey (a local barbecue and whiskey festival! ), some water got into my (non-sealed) 60D's rear control dial, leaving me with a major fluke the day before a big shoot. Fortunately, a dish of rice and a 150degF oven took care of that problem.
And finally, the main reason for this post. Two weekends ago, I shot a race held in front of a famous abandoned train station in Detroit, running two cameras. One was a radio-triggered remote on a small tripod with an 11mm lens. I'll let this GIF do the talking (note the camera starting in the lower right).
The resulting shot. Car's doing about 45mi/hr.
This is basically the highlight reel. There are many other tales of minor damage and lesser madness. In the interest of deciding if I'm on the lunatic fringe, and whether it'd be prudent to back off, I'd like to hear where others' limits lie regarding risking camera gear. How close to the action is too close? How much do you worry about weather sealing? How do you protect your gear?
