Canon File Info 0x0020 may be Anti-flicker

[Kameratrollet]

With Canon EOS R6 I could repeat this pattern. 10 pictures with anti-flicker off, 10 pictures with anti-flicker on, 10 pictures with anti-flicker off, 10 pictures with anti-flicker on. https://drive.google.com/file/d/1tP1jIcCyM2J5IoYJXPqLGpeoL6ogsScd/view?usp=sharing

Canon EOS 6D doesn't have the tag at all.
Canon EOS M5 has that tag but when I checked 800 raw files all of them had 0. I can't find anything about anti-flicker in the M5 manual.

Great, thanks.  I'll check my samples when I get a chance and see about adding this.

BTW, I'll move this to the metadata board because that's where discoveries like this should be posted.

Canon_FileInfo_0x0020 is also anti-flicker on both EOS 80D and on EOS R5.
enable == 1
disable == 0

Thanks @Kameratrollet

[Phil Harvey]

Thanks!

I think it may work to decode this for all models.  It seems that this is zero for models without this feature.

I'll add this to ExifTool 12.90
