Infuriating 1D Mark II problem

->> Hi all,
I seem to have run into a very irritating issue on my new mark II.
I was shooting hockey today and upon reviewing the files, I noticed a strange maroonish stain across about half of the pictures. Thinking it might have been a white balance issue, I did some tests to see if I could fix the issue.
The problem only seems to be occurring with white surfaces (ie the ice on the hockey rink). I shot a white light with the camera's fastest motor drive setting, and the pictures in the burst differed dramatically. Some were properly exposed, some were underexposed with a hint of the weird stain, and some were horrendously off colour and appeared as if I had dipped my sensor in 10-year-old sepia toner.
I have tried different batteries, different white balances including custom, going back to the default settings and even different memory cards. According to Photo Mechanic, I am at 21,082 actuations.
Any help would be greatly appreciated.
Thank you,
Codie |

| ->> codie, the lights in the arena are probably cycling and giving different balances, of course I may be way off base. but we've had these problems for years at night football games. |

->> Hi Chuck,
Thank you for your reply. The thing is, I did a test afterwards while shooting a stationary white light (I'll post pictures soon), and the problem persisted, even at a custom white balance.
Could that still happen?
Thanks again! |

->> Ahh, that does look very much like what I was experiencing.
Cycling lights... how does that work? Is that what the light in my test shot would be doing as well (it's just my kitchen light)?
I'd be very happy to know that my gear isn't messed up, and it can be explained easily.
Thank you all so much for your input.

->> Chuck and Mike: you were completely right. I just grabbed another camera and did the same test (I really should have done that before, I know. Panic mode!).
Same thing on every one. Many many thanks for fixing my evening.
And a big thanks to Guy Rhodes for posting that thread.
Let this serve as a reminder to all other students to test problems like this with more than one camera. Phew!
