EOS-M5 does not read out complete EXIF data from third party lenses

[JoFT]

I am using the EOS M5 since a couple of days. When starting to check my images I realized that the M5 does not get the informations in this case for a Zeiss Milvus 50mm f1.4. A Canon 7DMk2 is able to read these data....

I tried the Zeiss 100 MP on the Canon M5 using the Canon adaptor and the f stop, focal length and exposure time were all in the exif data. I use an Apple and just use the "get info" command to see this information. Is there more information that you are looking for?

These informations I get, but not the lens name.
