Swiss lens manufacturer Irix has announced its lens lineup is completely compatible with Canon EOS R cameras when attached using Canon's EF to EOS R adapter.

In an announcement post on its website, Irix says 'it is possible to control the aperture from the camera' and notes that all metadata is transferred properly from the lens to the camera including focusing distance and other exposure details.

Irix specifically mentions its 11mm F4, 15mm F2.4 and 150mm F2.8 1:1 Macro lenses.
