1DMKIIn Shutter Problem?

Tonight I experienced an issue with my 1DMKIIn. About half way thru shooting a volleyball match, every other image was black as if the shutter never opened. It was every other release. It recorded them as images.

I tried a few different lenses and changed the battery. No change, every other image is black.

Has anyone every experienced this or knows what the possible cause could be?

It does sound like the shutter has gone, as thats basically what happens

sounds a bit odd that if the shutter is gone, every second shot is okay...

might be worth taking the lens off, setting quite a slow shutterspeed & firing off a few frames to see what's going on. Sounds suspiciously like mirror-lock-up is enabled - only it wouldn't actually record an image for the mirror flip.

Thanks for the feedback guys. It is puzzeling. The camera had a shutter failure about a year ago after probably more than 500,000 releases. Acted a bit differnt then and the new shutter only has probably 8,000 releases. I had tried forcing the mirror lock up and it still has the problem of every other image. I have an E-Mail in to Canon and I'll see what they come back with.

Could be the shutter, but it usually looks like this when they go out:

Just had it happen to one of mine.

That's what it looked like in January when I had the shutter replaced. Canon did not give me any ideas and only suggest send in.
