About the C-mount#

Cine and CCTV thread mount; covers 1-inch and smaller sensors.

Adapting basics#

A lens can be adapted with simple tube spacers when its flange distance is longer than the camera's. With 17.53 mm, C-mount lenses can in principle go on bodies with shorter flanges such as Nikon Z, Pentax Q, Samsung NX mini. Bodies with this mount can take lenses from longer-flange systems such as Micro Four Thirds, Canon RF, L-Mount, Samsung NX, Fujifilm G-mount, Pentax Auto 110, Chaika, Leica M.
