Canon 6D mk II wrong Focal Plane X and Y resolutions

[Fabkzo]

Hi all,

I've been reading on this forum posts from 2017 to 2020 indicating that Canon write bad F"ocal Plane X Resolution" and "Focal Plane Y resolution" tags .
Indeed, I'm facing the same problem with my 50mm 1.8 STM recognized as a 50mm*1.519 = 75.95 mm .

Has anyone found a turnaround ? What are the good values to tag in order to get the good crop factore ( between 1 and 1.005 ) ?

Thanks in advance,

You can write FocalLengthIn35mmFormat to work around this problem.  Here is a command to set this to a crop factor of 1.005:

exiftool "-FocalLengthIn35mmFormat<${FocalLength#;$_*=1.005}" FILE
