EOS 6D Mk II anomalous behavior

I planned some photos in the blue hour photographing the moon near a windmill, planning it right down to what I wanted the photo to look like, where I was going to stand, what settings I wanted to start out with, etc, and when I wanted to take it; mode, exposure compensation, metering, etc.

 

When I triggered the shot, I got a >20 second time exposure despite having the shutter speed set at 1/125th of asecond.  I rechecked all my settings, repeated the shot and got the same results.  I've used the option to erase all settings:  got the same result.  Again, I reset all camera settings; reloaded my shutter, aperture, ISO, exposure compensation settings, retried the photo in Manual and Aperture-priority: same results.

 

I've gone so far as to look at every yellow, green, and orange menu, checking each option — but still get the 20+ second exposure; I've tried various lenses; different focus, white balance, metering, exposure compensation settings but can't eliminate the malfunction.


I've called Canon, retraced my steps, and haven't found a solution.

 

Ideas?

My first thought?  Operator error.  Your incomplete descriptions just simply do not add up.  You cannot set a shutter speed in Av mode.  Have you ever heard of Safety Shift?

" I've used the option to erase all settings:"

 

Did you also "clear all custom settings"?  If you didn't do that, you didn't totally reset the camera.

 

"...retried the photo in Manual and Aperture-priority:"

 

At other times does your M mode work as it should.  I.E. if you do a normal shot in daylight and you set a pretty normal 1/125 SS, does it work? Like pointed out above, you can not set a SS in Av mode so I, too, suspect operator error.

I believe that I stated I retried the photo in manual and Aperture-priority. Perhaps the better explanation would be that I retried taking the photo first in Manual mode THEN Aperture-priority.

 

My mentor also has the EOS 6D Mk II: we sat down the next morning and looked at every menu feature to see if he could replicate the problem using his camera: the effort was unsuccessful.  I haven't yet attained the level where everything I do is perfect, but I'm ecstatic to learn that I don't have the skills to troubleshoot a problem.  Thank you.

Yes, I did twice — as did my mentor after my second reset...  We checked every switch, each menu's features/options.  We both went through the menus on both cameras to check for discrepancies or anomalies between the two.  We sat down with a menu tree I developed to learn the camera (a holdover from working for Boeing).

 

Canon grilled me on the phone and our efforts to find the anomaly or operator error were unsuccessful.

"When I triggered the shot, I got a >20 second time exposure despite having the shutter speed set at 1/125th of asecond."

 

Triggered?  As in remote trigger?  I assume that you also tested without a remote trigger if you were using one.  

 

Make sure that the shooting mode dial is working properly.  I assume that it is good, but the behavior you describe is consistent with it being off by one click.  What happens if you take a regular photo in P mode?

 

Did this camera body ever work properly?

This doesn't sound promising does it?  Smiley Sad

Reaching now, do you or did you have any non-Canon items connected o the camera? Battery grip? Batteries? Anything? Any thing at all even like a computer monitor? 

 

The camera was all Canon?
