6D Mark II cannot read it's own pictures

jnelson1078 — Fri, 27 Dec 2019 22:25:54 GMT

Took many pictures with my 6D Mark II, when I look at the photos in the image viewer on the camera, all I get is a big question mark. My updates (both Canon and Mac OS) are all up-to-date. These are photos that will never occur again, is there a way to recover the files. Other apps (such as the latest Photoshp say the file format is not recognized and Finder flat out states the file cannot be opened. Canon Professional 4.0 gives me the same thing as the camera. Please help.

There are two possibilities worth considering. One is that something is wrong with the camera.

But on the information you've given us, it's more likely that the problem is in the (SD?) card. Is it one of those micro cards that uses an adapter to fool the camera? If so, get rid of it, and let us know whether that solves the problem. Otherwise, try one or more additional cards, making sure that you've formatted them in the camera before using them. If that solves the problem, your current pictures are probably lost, but at least now you know. If it doesn't. there may be something wrong with the camera, and you should try to get it fixed - either by Canon or by a reputable 3rd-party repairer.

Is this a new problem in a camera that used to work? Or has it been this way since you got the camera? Any additional information you can provide may prove helpful.

Do the files show up in an Explorer window in a desktop or laptop computer? If so, what are the sizes of the files and what are the file name extensions (.jpg, CR2, etc.).

The files are listed in explorer, but they will not open.

Download Canon DPP and see if that will open the files.

. . .And again, approximately what size are the files and what are the file name extensions?

I do not know about a MAC, but Windows will not let access the files in the camera as if it were a thumb drive. You should have gotten an "Access Denied" type of message. I guess that is what the question marks might represent.

Try removing the card from the camera and use a card reader. Most laptops have an SD card reader already built-in to them. It

Works fine for me. 1D X Mark III connected to Windows 10 PC.

"Works fine for me. 1D X Mark III connected to Windows 10 PC."

Yes, you can browse. But can you actually open a file? I think the camera has them locked for access.

If its a JPEG and you double click the Windows app opens.

If its a RAW file and you select Open it needs to be told the software you want to use.

Was the EOS Utility running? It should kick you out if it is.

No. The auto start feature is disabled.
