TS-Optics Canon RF / EOS R and RP camera T-ring — M48 × 0.75
This T-ring connects a Canon RF / EOS R and RP camera body to a matching M48 × 0.75 telescope-side interface.
Mechanical spacing
The manufacturer lists an effective adapter length of 9.8 mm. For the RF version, the specified distance from the M48 interface to the camera sensor is 29.8 mm; it is not the same as the ring body length.
Camera fit
This version is for the Canon RF / EOS R and RP bayonet. Similar camera names do not make Sony E, Canon EF and Canon RF rings interchangeable.
Compatibility notes
Canon RF (EOS R/RP) adapter, not EF or Sony E. 9.8 mm adapter length and 29.8 mm M48-to-sensor distance are different measurements.
