6D - Weird Image Line

Need some help from POTN.

I was at the the museum today with the family and in two specific display cases, this issue of a line in the image kept happening. it was not consistent and was random around the image. Is this a shutter issue? Or maybe a light cycle of the display case? It seems like it is in the camera since it remained in the same orientation of the camera. It only happened on these two parts of the museum. I was shooting aperture priority at f2.8.

Thank you,
Dave

I'd say your shutter is failing. How much use has this camera had?

About 25k actuations. It was only on these two specific display cases. I even went back and tried again after it stopped and it happened again.

In both the shutter speed is quite high. It could easily be the lights cycling. S;ow down the shutter to 1/60th and it will go away if it is the lights cycling.

Actually, looking at it closer, I don't think it's lights cycling. Looks more like shutter sticking.

Wouldn't the shutter look bigger, and be at an angle?

That's why at first I though it was something else.

Do you have and/or used a EF-S lens on your 6D?

Nothing to add to the original post However, this comment caught my attention, does the EF-S lens on a 6D matter? If so, why?

Thanks,

I was using a 24-70 2.8 when it happened. I never saw it before and I haven' seen it since. I even tried using the same settings in manual mode.

You can't even physically mount EF-S lenses on a Canon full frame.

Kek & Kauket at play eh?
have a suspicion that it's fluro lighting causing the problem rather than shutter - both lighting sources appear to be at 90 degrees to the dark line. If you can get back and do some test shots at differing shutterspeeds you may be able to reproduce the problem & see how to sort it. Which museum was it?

It doesn't look like shutter to me. In the portrait orientation shot, were you holding camera grip up, or grip down? The 'line' is only in the right place to be shutter failure if you had grip down. If shot grip up, it can't be a shutter issue, it is on the wrong side.

It was the Houston TX Museum of Natural Science.

I do grip up in portrait orientation.
