Photoshop CC 21.2.2 changes camera lens used in the EXIF data file

I have noticed my EXIF data file has the wrong lens used for the image in question.  For instance, if I am using my Canon 7D Mk II with Canon 100-400 II lens, it might list a Sony 200-600 lens as the lens used.  Sometimes when using my little underwater Nikon AW1 with 11-27.5 lens, it will also list the Sony 200-600 lens as the lens being used.

 

What is going on?  Any ideas why my EXIF file would show the wrong lens?

Exif data is created in camera and most manufactures do not store the lens information like make and model in exif data that seems to be optional. Camera manufacturer do store that information  that information in their Camera meta data if the lens report the information to the Camera body firmware.  Adobe RAW process may extract the lens model informated from the Camera Manufactures Camera meta data and added it to exif data.  So what is in exif date is mostly Camera Data but may be changed over time by applications like Photoshop Bridge, ACR, Scripts, Utilities like EXIF tool RAW data may not be changed the same is not true for meta data.  If may be hard to track what did what the a files meta data.  PS File Info  may be helpful.  Here you see what CS3, CS6 and PS 2020 report as Camera data for the sane RAW file.  You will see only CS3 report the Max Aperture of 2.8.  All report the lens is is a fixed focal length 300mm lens.   You will also see in the Raw data the follows the Lens Information is not actually in EXIF date it in Aux Data and CS3 had to decode the Len Info Data to see it has a max aperture of 2.8. However three different versions of ACR are involved here.  The RAW Meta Data I posted is how ACR 1 2.4 Edited it.   I'm sure that CS3 ACR and  CS6 ACR 9.1.1 versions would be somewhat different. If I shot Jpeg there may not be any  lens infor data in  the files meta data for all I know.
