• Front side - accepts a Canon RF (EOS-R) lens
• Rear side - CS-mount male thread

Machined from high quality aluminium alloy.

This adapter allows using manual Canon RF lenses on cameras with CS mount. Infinity focus is preserved.

This is a dumb adapter (no any electronics), and your lens should be able to operate in fully manual mode therefore.

Important notes:

1. Only manual lenses (like Laowa or TTArtisan) will fit this adapter. Standard lenses with electronics have a bit too long rear part, and will NOT fit.
2. C-mount and CS-mount share the same 1"-32tpi thread, but they have different flange focal distance. This adapter is purposed for CS mount with shorter FFD. A lens will focus to very close distances only, if mounted to a camera with C mount.
3. We still can't make female bayonets properly, so this is rather a semi-permanent mount than a quick-change adapter. The lens mount is held by 3 cone-tipped screws that hold the mount lugs. These screws will damage the lens mount lugs a bit.
