Hi,
some further observations on a Canon 5D3:

   
• I shot two pictures with no change in subject or camera settings. One as RAW one as JPG.
  For the JPG "Canon Image Size" reports as "Large" correctly.
  For the .CR2 it reports as "Unknown (-1)"
• Both files show the "Continuous Drive" reports back as "Unknown (9)". The pictures where shot in "One-Shot" AF mode and Single shot silent drive mode.
• "AEB Shot Count" outputs "Unknown (5); 2". While none of the shots were done in auto exposure bracketing mode, the setting of the camera for AEB is currently set to do 5 shots. If I change it to do 7 the output is Unknown (7); 3. Two shots is "5; 1" and Three shots is "7; 0". Note the last ones have no "unknown".

I see -1 for CR2 images from many models.  But I also see -1 for some JPEG images, so it doesn't just mean "CR2".  Canon often uses -1 to indicate that the value is not applicable.

• Both files show the "Continuous Drive" reports back as "Unknown (9)". The pictures where shot in "One-Shot" AF mode and Single shot silent drive mode.

It would be useful if you could figure out what this means.  Are the other drive modes decoded properly?

Thanks.  I think I understand, and this will be decoded properly in the next release.

It seems you havent got the silent drive modes yet.

Unknown (9) is "Single, Silent"
Unknown (10) is "Continuous, Silent"

The rest is fine.

Thanks.

What I had already was this:

            0 => 'Single',
            1 => 'Continuous',
            2 => 'Movie',
            3 => 'Continuous, Speed Priority',
            4 => 'Continuous, Low',
            5 => 'Continuous, High',
            6 => 'Silent Single',
            # 11 - seen for SX260
            # 32-34 - Self-timer?

So either number 6 is wrong, or there is something different with the 5DmkIII silent drive.  I can't remember what model was used to decode number 6.
