This past weekend, I was on a planned shoot and set up to get images of thee women riding some very nice looking horses in a field. I was using my hitherto trusty Canon 5D Mark IV. I had mostly filled my SD card and switched it out for a new similar formatted card. Suddenly, my 5D Mark iv hiccuped and started over exposing every single frame and filling frames with white squares. There were no usable frames. Has anyone had a similar experience? The folks at Canon were no help and all their repair centers are closed. Dan Blackburn

How were the images on the CF card in the camera? The camera has two slots in case there is a problem with one of the cards.

What happens when you use another SD card, given the SD card is a likely cause?

Were any of the RAW files editable?

Have you considered posting an example or two JPEGs, being sure to store the file, so the EXIF data can be inspected by other members?

Your camera is a computer with a light sensor attached. Try rebooting. Take out the battery, turn it on, wait a minute or two to discharge any capacitors, turn it off, put the battery in and try shooting a photo or two. This might not work but it sure can't hurt to try.

You did turn the camera off when you changed card, correct?

Every Canon I have had, including the 5DIV, shuts down when either the battery door or card door is opened. With my memory being what it is, I've changed cards, batteries, and lenses without shutting off the camera with never a problem.

Never noticed, I always turned off the camera.
Interesting though. Evidently there's no problem without shut-down stabilization when either is removed before the system is stable.
Yet.

Canon's in-lens stabilization is only active when the shutter button is depressed halfway.

Isn't that settable as continuous/on shutter press?

Also go to Canon support and download the latest firmware then load it, even if you have it it could be corrupted for some reason so load a fresh copy.

Almost forgot, I had mine do something similar. I had been shooting in very dim light the day before. All my frames were vastly over exposed. Turns out that "lock" on the bottom right had somehow been moved to the lock position (rubbed against something) and it was locked on 12800 ISO.

Is it possible that you had the Exposure Compensation set way to the right and didn't notice it? I've had that happen to me before. It would be helpful if you could post an example (and store original).

I don't shoot Canon but, I'm with Basil. It certainly sounds like Exposure Compensation was set high on the plus side. I have to be very careful with my Sony A7R3. The EC wheel is very close to the shutter speed wheel. If I don't keep an eye on the EC in the viewfinder, it can cause a lot of overexposure.

I have, on several occasions, been shooting on my 5D4 and realized my EC was not at zero.

Not that I have ever seen in any menu. I have had a good number of stabilized Canon lenses and the only time I have ever seen the effect of the stabilization is when the shutter release is pressed halfway. What the deal is with BBF I can't say since I never use it, but, the chance of someone using BBF and then deciding to change lenses in the middle of the shot seems pretty remote. My EOS R came with the constant auto-focus feature activated. Anytime the camera was on it was trying to focus whether you were taking a picture or not. I imagine there is some use for that feature but I quickly disabled it. I have no idea what it would be used for except to wear down the battery and wear out the auto-focus mechanism.

Does it have a touchscreen?
Maybe you pushed the iso to the top?

I had something similar w a G-7 and didn't realize I had touch screened the iso to the top number.
Disabled the fool thing for good. Annoying function really.
