Odd exposure shift on 5d

->> Hey guys and gals:
Did some digging on this but didn't find much, at least on here and the more recent message board stuff.
So the other day I noticed this funny thing with my 5d (MkII). The exposures shift like every other frame. This was in manual, and looking through the EXIF info in Photo Mechanic, I see that nothing changed -- not the ISO, shutter speed or aperture. But, like every other frame is almost a full stop brighter.
Seems to only happen on motor driven sequences, and it happens with a variety of lenses (tested that one).
Any ideas? I'm probably just going to send it to Canon, but I'm kind of curious how big of a problem this is? I tend to keep my frames on the dark side, anyway (expose for the highlights), so I'm not getting hosed by this or anything. It's more of an annoyance at this point. But, I'm worried it could be like a warning side of something bad.
Thanks in advance!

| ->> are you shooting under football lights? or volleyball lighting? you don't say if the histogram shows a shift, so I assume, yes, that assume.. that it could be it..We have a stadium nearby in which every frame is a color shift and light level shift. 6400 1/550 f2.8 and there it is. Some power to the stadium lights varies so you get proper and under exposures all over the place.. |

->> Andy, good guess, and I meant to put that in my original copy.
All photos are full sunlight. No tungsten, incandescent, or other fugly, fake light.
Thanks for the note though. How are things out west? Good I hope.
Cheers amigo,

->> I had this exact same thing happen with the 1D mark IV. I was shooting manual, everything the same ISO, shutter, aperture, and with a burst there would be a shift of between a 1/2 to full stop brighter. It was pretty random on when it happened...I would have a burst where all exposures were the same and then a burst where almost every other shot looked exposed differently. This was also happening during the day but I noticed it in full sun and full shade.
I happened to be borrowing the camera from canon so I never found out what was wrong with it or why it was happening.
Anyway, I wanted to let you know that you aren't the only one that has experienced this. |

| ->> Sounds similar to a problem I'm having with my newspaper-issued Nikon D2H, where in my case the first frame of a burst will be either completely black or a stop or two darker... I have heard it's a shutter issue, I assume it's the same across brands too (tho leave it to Nikon to even have a dying shutter go opposite of Canon, under exposed on the first frame instead of overexposed on others ;P) |

->> This happens with the Canon Mark IV because for some reason it is shipped with a default custom function called "Auto Lighting Optimizer" (C.Fn. II: 4) in the ON position, which messed up many of my pictures with my new cameras in spring training this past March.
Random hot frames in motor driven sequences with camera set manually- this drove me CRAZY!
It took many phone calls with Canon to figure out that my cameras were ok. SCARY.
Turn it off and you will be happy.
Good luck! |
