• Front side - C-mount female thread (1"-32tpi)
• Rear side - Fuji X male bayonet

Machined from high quality aluminium alloy.

This adapter allows using some C-mount lenses on cameras with Fuji X mount. Infinity focus is provided for a properly adjusted C-mount lens.

Important notes:

• Since the C-mount flange focal distance is a bit shorter than the Fuji X FFD, the adapter is recessed to provide infinity focus. The recession diameter is 39mm. Please verify that your lens has a smaller flange; otherwise, it will not fit the adapter properly. Please refer to the drawing for other dimensions and compare them against your lens(es).
• The lens witness mark position is calculated to be on the camera top for lenses from Bolex REX cameras. It is not guaranteed that your particular lens will have the witness mark at the correct position. But many of C-mount lenses have rotatable mounts to adjust this position if necessary, so you'll be able to fgix this if necessary.
