Canon CM-V1 Locking EF Mount Kit 3937C001 Photo Video

The Canon CM-V1 Locking EF Mount Kit replaces the Canon EF mount that comes attached to your C500 Mark II.

The locking mount maintains the same electronic functionality of the standard EF mount, but locks your lens into the mount to prevent play.

Cinema lenses, especially zooms, require that lenses maintain a precise distance from the image plane for best results; any play between the lens and mount can cause the lens to suffer from poor optical or mechanical performance.
