But these tags actually exist in the images

Code: [Select]
exiftool tmp/leica_m10_p_03.jpg -Lens
Warning: Bad length ICC_Profile (length 3144) - leica_m10_p_03.jpg


But for another file it works fine:
Code: [Select]
exiftool tmp/leica_m10_p_49.jpg -exiftoolversion -Lens
ExifTool Version Number         : 11.32
Lens                            : Summicron-M 1:2/35 ASPH.

"Lens" is an XMP tag that wouldn't exist in an original image.  Add -G to my command to see where the tags are stored.  XMP tags are generally added by Photoshop and aren't written by the camera.
