Will your insurance pay for a rental while its being repaired? If they won't cover the damage, I'd sure hunt for different insurance.
The damage definitely goes beyond cosmetic, water and light are going to pass thru that hole, Cameras have light barriers, but not for holes punched in them.
I have to call first thing in the a.m. to see. Hopefully though, I have the insurance through PPA but the upgraded Photocare +
Congratulations, it seems that you were very professional about this, but then I guess a bad reputation would cost more than the camera, not easy to think like that in the heat of the moment though!
With respect to what Mt Spokane has pointed out, I would test the camera in bright light to be sure that it is not compromised before trusting it for another wedding!
I know that the 1D range are reputedly built like tanks, but a severe shock that would be required to cause that much damage may have jolted the focus sensor or other critical components out of alignment. I would do some very thorough tests to check critical focus and displayed focus point position with respect to what you actually focus on at the very least.
I always thought that big bulge was there to house the pentaprism, is that ok, no signs of chipping, cracking?
If the camera really is ok after that it would serve to highlight the robust nature of the build of this machine.
I would hope that your insurance would cover repair without quibble, and the cost of a rental if yours is injured in the line of duty, if not, unless it was openly specified in the agreement, I would want them to explain why I should continue to give them my custom.
thanks Graham! Yes unfortunately keeping my cool ensures I keep food on the table, the last thing I need is for them to only remember me flipping out on a guest that knocked my gear onto the ground. As far as testing goes, I shot with it a little today, its raining all day where I am so It was just some indoor stuff with different ISO and Fstops on various lenses. Everything seems to be working as usual. As far as the pentaprism I looked at a few online diagrams of some 1DX insides and it looks like the area that cracked actually has nothing in the immediate area other than a electrical ribbon and no there is no signs or damage to anything in there that I can see. I am really hoping insurance pulls through with this one and doesn't screw around.
