Canon EOS 10D Shutter getting in the way on fast shutter speeds
On shutter speeds quicker than 1/750s there is a dark band at the top of the picture. Increasing the shutter speed makes the band wider until at 1/1500s there is no picture. It appears the mirror is either not getting out of the way fast enough, or is returning back down to quickly. Any suggestions welcomed.
Re: Canon EOS 10D Shutter getting in the way on fast...
Does this problem occur only when you are taking flash photos? You may be exceeding the shutter's maximum flash sync speed, one shutter curtain is blocking the flash exposure. At speeds below max sync you get full frame exposure, correct?

Shutter speed too high...1/250 violates the max flash synch speed of most FF cameras....the shutter is not fully open at that speed when the exposure is made, and you are seeing one curtain at the black band.
You need to understand the relationship and teractivity of aperture, shutter speed and iso. In Av mod, you choose the aperture and the camera makes thw shutter speed agjustment, In Tv mode, you set the shutter speed and the camera makes the aperture adjustment, In manual, you have to set both shutter speed and aperture manually. If the ISO mode is set to AUTO, the camera chooses the sensors sensitivity to light automatically. Change to specific ISO (200-400 for daylight and 799-1600 for night). Take a picture in AV mode and note what shutter speed the camera chose. Then switch to TC mode choose the same shutter speed and see if camera chose the same aperture(f-stop) you chose in first shot. Change to Manual and choose same f-stop and shutter speed the camera chose for you in the other modes. Compare all three photos. They should be almost if not exactly the same exposure wise. In Tv mode choose a dlowers shutter speed, In Manual choose a combo of slower shuuter and wider f-stop(smaller number). Read your manual.
Which mode are you on? When you zoom in, the maximum aperture size decreases to f/5.6 in the kit lens. Sometimes it may be too dark or shutter speed too slow so the camera doesn't shoot. If you're in "P" (program) mode, full auto mode or any of the Basic Modes, the aperture/shutter is auto. In other modes (Av, M, etc) you can turn the dial on the top of the camera to adjust shutter speed to a lower number.
There is an action shot setting on the wheel on the top of the camera. If you want to manually control the camera:
-Select Tv mode (shutter priority mode)
-Select a fast shutter speed
-Manual focus on what you want to take
-Take multiple pictures so one will be good
That problem is normally associated with having a too high shutter speed when using flash. If it happens in any mode, with or without flash you may have a shutter blind issue.
Test the camera at various shutter speeds and compare the results. If this black area is consistant across different shutter speeds, send it in for repair. It is most likely the shutter curtain not making a pass across the sensor fast enough, still obscuring the sensor when a photo was taken.
One of the shutter blades is faulty or is being obstructed. Either that or you're using flash to take pictures but using too fast a shutter speed, most SLR's have a flash synch speed of 1/60 or 1/125 of a second.
The first problem will need a professional repair, but it may be a fairly straightforward one. The second problem would require that you read the user manual for both the camera and flashgun.
I would suggest to check the lens inside. there might be some kind of small item inserted inside. check if this happens with no zoom and full zoom. if the problem persists, I would suggest to first have it checked with another lens just to make sure it's a lens matter. Then decide if you need to send it back or buy a new lens.
It's a shutter problem--it's not the amount of light per se that causes it, it's the shutter speed. This issue often only shows up at a few shutter speeds.
My 1dsII does it around 1/125, although not nearly as badly. Apparently the shutter is bouncing or hanging up at the end of its travel. Sorry, it's either send it to Canon or learn to live with it.
