The problem with banding is eventually you'll have no choice but to send the camera in for repairs as it will continue to do this with each ISO setting until you can't use the camera any longer without this line being in place. The best way to test it is to take a few shots per ISO setting. If you see the line is in more than one ISO setting it's banding. Your best bet with your camera being the Mark III, is to send it in for repairs before it goes any farther down hill. Also, could be a manipulation issue which don't happen very often. But basically what happens is the camera tries to manipulate a brighter area and darken it to blend, also a sensor issue. Canon has had 2 minor cases of it so far and Pentax has had many (more than 10) If you review the photographs they display they are very similar some being on the sides of the photographs and bottoms even a couple being through the center at about the same with. There was only one that went about half way across and then blended in.

JWilliams, Thank you so much for the information as I was lost and I think your right as this Camera is too expensive and Canon already said they would clean the Mark III for me for free. I have also already sent it back once for a recall but can't remember if it was a sensor issue or not. I'm going to call canon right now. Yea last night see it was dark and I saw no line I might go out on the porch and take some shots now. But it doesn't matter It's going in the shop. Thanks again

Yea I called Canon and they want me to send it in. Will see if they'll charge me or not, not sure what a sensor will run me or if it is a defect known in the Mark III as was mentioned earlier.

Shutter curtain is getting hung up as it travels, overexposing that top section by leaving it open longer.
Canon repair.

Were you using a hood on your lens also?

That should have been first and second curtain. I don't think that is your problem. What it looks like to me is that your shutter speed and F stop were not correct for the photo you were taking. ISO more than likely has nothing to do with it. Go to your metadata and check all the settings and let us know what they were, then we may have a lot more ideas as to why it happened.

You may want to try to "Reset your setting". Go into your menu and find Clear settings. Place your camera in the "P" mode and clear settings. Turn off camera and take battery out and then turn camera on and hold shutter button down for about a minute. Turn off camera and place battery back in and turn camera back on. Take some shots and see if this helps.

What is a Shutter Fist


I think that your camera need some major testing. Ok Send it to me and I will check it out. I shouldn't need it for more then a year or two.

I'd say it is definitely a sensor problem. Memory problems would have digital artifacts like blocking, sharps lines or noise.

Tiger1640 Thank You I think I will try this before sending it into Canon, I don't want to be without it and much less sending it some where even if it is insured. Thanks again
