EOS 5D Mk IV has a Scale Factor to 35mm of 1.2 - for a Full Frame Camera ?

[Andy Quinlan]

Hi Phil,

I am attaching a Format File I use and its Output for two Cameras with two outputs, one for each camera.
a) EOS 5D Mk IV
b) EOS 5D Mk III

Output f)  for first Image from a canon EOS 5D Mk IV shows Scale Factor to 35mm as 1.2 and canon state this is a Full Frame Camera.
Can you please check outputs  c), f) h) from both Full Frame cameras

Many thanks for your help.

Kind regards
Andy

Hi Andy,

I don't have to look at these.  There is a known problem in the FocalPlaneResolution tags stored by some Canon models.  These incorrect values result in the scale factors that you have observed.
