Compatibility of Zeiss ZE lenses and Canon RF cameras

[TEQUILA]

Please respond to those whose RF series camera does not detect the Zeiss ZE lens? I have two cameras. One is a Canon EOS 6D and the other is an EOS R8. The EOS 6D camera is equipped with a Carl Zeiss 50 1.4 ZE lens. But the R8 camera does not see the lens. There is a dash in EXIF.

I use the original Canon EF-R adapter. Zeiss lenses have electronic contacts. Canon R8 controls the lens aperture and allows the use of focus assistant. But the R8 camera does not write the name of the lens in Exif. The Canon 6D camera writes the name of the lens into the exif. I want RF system cameras to register the name of the Zeiss lens in Exif

Unfortunately, like most camera makers, Canon do not take responsibility for 3rd party equipment that people attach to their own equipment.   This is not unique to Canon, the same thing applies to all major vendors.

Canon EF defines Zeiss lenses. They are not detected only by RF cameras

Greetings,

Does the R8 have a setting that allows "Release shutter without lens attached"?  This might be in C1 settings if I recall.  You can try that if available.  

As Trevor said, some 3rd party lenses may not be supported.  A manual lens doesn't communicate, so you'll have to test it, and see if it works or not.

That fact that Canon cameras worked with Zeiss lenses is more a function of the fact that Zeiss themselves did the work to make that happen. The onus is always on the 3rd party, not the OEM.  The fact that Canon have changed their platform may cause those compatibility efforts by Zeiss to be compromised, I would certainly not expect that Canon will take any action on this from their end.
As Rick suggested, you might try some measures to turn of features specific to the RF mount lenses.  Also, what brand adapter are you using from the lens to the body?

What do you mean by  "Canon EF defines Zeiss lenses. They are not detected only by RF cameras".

What do you want your lens to do ?  It has an EF mount, but it is a manual-focus lens, so aperture-setting is the only auto function. You also have not said what EF-to-RF adapter you have. 

So, a third-party lens that Canon cannot guarantee function of, and an aftermarket adapter that is not guaranteed by Canon to function with its camera. Plus, even with a Canon adapter you could have trouble with an aftermarket lens.

If you want to provide detailed info, possibly there is more to be said. Otherwise, give it up.

I only use original Canon adapter. I think Canon will not agree to the meeting and the lenses will never be registered in Exif. I wonder if the Voigtlander Nokton RF 50 1 brand will be registered in the Exif file? Zeiss and Voigtlander lenses are manufactured in the same factory. And even their design is similar

Zeiss lenses from the Classic line communicate with the camera, take excellent photographs on Canon RF cameras, can use a focusing assistant, control the aperture, and confirm focus. But the lens brand is not registered in the Exif file

It seems to me that you are deliberately adding fuel to the fire to close the post. Have a nice day and good mood

NO third party lenses or other accessories are supported by camera OEM companies. I am not sure how to make that clearer.
