Okay... now THAT is impressive to me. A simple acceptance of the camera equipment as a disposable tool required to do a job. That event must've been a hoot for all involved. The nearly submerged chaps in the mud look to be having the times of their lives Great series. Kudos to the photographer.
Hope that he had a filter on that ultrawide so that he can hose it off without fear. He should be able to gently wash off the 1-series, but I recommend a damp cloth approach on the 5D2. I don't know that it's as willing to accept rinsing as the 1.
That would be a "clean day" for me after shooting motocross in the mud! I slipped, fell, and landed on one of my 1 series bodies at Budds Creek. The entire body, 70-200 and all, was completely submerged in a foot of mud. It made that sound like toilet plunger when I pulled it out. I wiped it off, changed the filter, and kept shooting without missing a beat. I think it's funny the way some FM'ers baby their gear.
The 1d should be fine no problem
damn things are tanks!
mud shmud canons can take anything
I put my 5d all the way under water and it still works fine just needed a bit of drying.
