Possible Problem with 1Ds Mk II. Opinions?

It's the shutter starting to go. Seen many pictures of people posting images with that white line on top. Take more images at faster shutter speeds, see if the white line is more pronounced. Although it may just be starting to go and not always show up.

Good thought. That's the most plausible theory I've heard so far, but if so, that's a concern. This camera has fewer than 2200 shots on it. I'll try it again with different shutter speeds to see if that makes a difference. Thanks.

But if it was the shutter shouldn't it be consistent with the other lenses as well?

Thats what I thought too. If its only happening with the one lens, doesnt it have to be that lens causing it? I would have thought so.

Logic would suggest that. Whatever it is, it's either a problem with the sensor or near the sensor. If it isn't the sensor itself, then the shutter is the next most likely suspect. If it was near the bottom of the image instead of the top, we could even consider the mirror, but that's not the case.

I have a few different scenarios I'm going to try tomorrow (or as soon as possible). I also want to see if it shows up on my 100-400 on the long end.

There are sure a lot of possibilities, although none of them make a lot of sense, especially because the camera is so new.

Do more tests and then let's see.
When did that happen exactly? did you drop the lens or something wrong happened to the lens?
more tests will show if there is really a problem or not, sometimes problems occurs in lens or camera for a while then disappeared, so don't panic and sure we all here will try to find the solution, it can happen to anyone here so we should be careful and aware about it for next time appearing.

look like a shutter issue to me. Sorry to see you got a problem. Hope I am wrong.

I'm going to see if I can duplicate the problem again with any other lenses. I don't think there was any specific trauma to the camera or the lens. I'm usually pretty careful with my equipment.

Thanks, Dante. I'm not horribly upset about it---more curious than anything. If there's a problem, I'll just get it fixed. At this point, it's more of an intellectual exercise trying to figure out what happened.

Yes Belmondo, it is a good idea to figure out the problem, who knows, it could become bigger, so fixing it now better than waiting to grow th problem, and i like to keep all my gears as good free of problems as i can.

First thought would be shutter bounce, but that should show up on the other lenses as well. Next would be internal reflections somewhere. Close enough to anyone else with either a FF or a 400 f/5.6 to run a comparison? Maybe even try borrowing a film body if it comes down to it.

light leaking in somehow? any damage to the lens?

when my shutter went it was more of a curved highlight from top to bottom of the image but that was on a 300D.

strange one that.

Shutter/mirror issue.

This same effect but a dirty sensor was posted a week or so ago. Where it showed with only one lens to the neaked eye. This guy had a smudge on his sensor that only showed with the 100-400 I believe. And could only BARELY be visible on another shot with another lens.

Considering the season (not a lot of shooting in America right now) and the seriousness of this, you need to locate a cardboard box immediately and get it to Canon.

We have an excellent Canon repair facility a couple hours drive from here. I'll probably drive it over personally. Perhaps when they see the distraught look on my face, they'll take pity and do a rush job for me.

I still want to play around with it and see if I get the effect on any other lenses.

Could be that the only reason that you're seeing it with this lens (so far) is that you're shooting at a slower shutter speed with the 400/5.6. Test it with a multitude of shutter speeds to see if it affects the results.

The shutter is going, and starting to bounce at the end of its travel. I see a Canon in your future...

AIR, some Ds's have this very early for some reason. It band is a smaller one than others I've seen, vertically, so a shorter lens with a greater angle of incedence than the 400 may
not show it. It also tends to be quite intermitant at first.
