Bit confused here, all my Canon EOS bodies (including 5D III, 6D, 1D X) show a MirrorLockup tag (value enabled or disabled) in the exif data, but I can't find anything like that in metadata from 7D II raw files. Any ideas or similar experience here?

A 7D II CR2 file from my camera can be downloaded here: http://www.filedropper.com/7d20367

Hi Niels,

It is likely that this information exists but hasn't yet been decoded for the 7DII.  To decode this I will probably need a few samples with this setting changed in a known pattern and all other settings unchanged.  If you take a set of 7 pictures (smallest JPEG possible) with the mirror lockup on-off-off-on-on-on-off (in that order) and upload them, then I'll take a look.

...where DIR is the name of a directory/folder containing the images.  On Mac/Linux/PowerShell, use single quotes (') instead of double quotes (") around arguments containing a dollar sign ($).

Thanks  ;D
A zip with 7 JPEG's in the requested sequence can be downloaded here: https://we.tl/yJTs3RW1ob

Got them.  I'll post back here after I've had a chance to look at them.  Give me a day or two.

Interesting.  This information is stored in the Canon customs settings for other models, but not for the 7DII.  Perhaps it is no longer set in the custom settings menu?

Anyway, looking at the files you sent I find a few bits that change according to the pattern, but it isn't obvious that any of them are what we are looking for (one would expect a whole byte dedicated to this setting, so a byte value alternating between 0 and 1 would be nice.  However, this is what we get (the output is from a "multi_diff" script of mine):

Just to make sure, I have uploaded a new set of images, this time without lens attached to the body. Would you mind to have a quick look at these files as well. The on/off-order is identical to the first set. They can be downloaded here: https://we.tl/agPMTL6sGK

I also checked CR2 files of various models (from downloaded files) released in the last couple of years:

700D: Q2 2013 (mirror lockup tag is there)
70D: Q3 2013 (can't find it)
7D II: Q4 2014 (can't find it)
750D: Q1 2015 (mirror lockup tag is there)
5Ds: Q2 2015 (can't find it)
80D: Q2 2016 (can't find it)
1DX II: Q2 2016 (can't find it)
5D IV: Q3 2016 (can't find it)

No luck with these images either.

Where is the mirror lockup setting in the 7DmkII's menu system?

- Phil
...where DIR is the name of a directory/folder containing the images.  On Mac/Linux/PowerShell, use single quotes (') instead of double quotes (") around arguments containing a dollar sign ($).

Hi Niels,

Ah.  It is in the shooting menu now.  For older models it was in the custom functions.  This explains why it changed in the metadata.

Does that mean that the setting is stored somewhere in the CR2 file?

All I can say is that I haven't been able to find it.  At this point I wouldn't bet on it being there.

Is there somebody at Canon who can confirm if it's there or not? Do you know if DPP software can display the setting? If it's there, Canon's properietery software should show it :)

There is nobody at Canon who will be of any help.

I don't know if DPP displays this.
