Canon RA Adapter question

Greetings

Can someone tell me whether the new Canon EOS Ra Full Frame Mirrorless Camera Body For Astro Photography needs a new T-adapter?

Cheers Petra

If it uses existing lenses then probably not.......but
Being I am an idiot I see it is a Canon RF lens mount so the answer is yes

Canon RF Lens Mount

Beginning with the lens mount, the EOS Ra supports Canon's line of RF-mount lenses. This mount is characterized by its wide 54mm diameter and short 20mm flange-back distance, which promotes the ability to design lenses that are both faster and smaller than their SLR equivalents. The mount also incorporates a 12-pin electronic contact system for more sophisticated autofocus and image stabilization capabilities. This mount design also lends full compatibility to existing EF and EF-S-mount lenses via an optional EF-EOS R Mount Adapter.

Using the RF-EF adapter, no new T adapter is needed, you can just use the Canon EF - T ring adapter.
And the RF-EF adapter also allows you to use all EF(-S) lenses on an EOS R(a).

Short answer: Yes, you need a different adapter

As mentioned earlier, if you already have a EOS R to standard EOS lens adapter you can use a standard EOS T adapter
