Revolva EF is a combination ND filter and intelligent EF lens mount for RED® DSMC2®. Converting from the robust 4 bolt DSMC2 mount to Canon EF, Revolva performs double duty by providing an integrated ND system with cinema quality optics. Filter cartridges are loaded with a four-position rotating filter. Revolva EF is compatible with any existing quick-change Revolva cartridge, for best of class ND right where you need it.

The mount is optimised for strength and long life. Stainless steel and aerospace grade aluminium are used throughout. The EF mount is factory calibrated for accurate backfocus.

All EF lenses approved as compatible by RED will work identically with Revolva EF, including all supported electronic functions.

Note: Revolva requires at least one cartridge to function, but is compatible with all pre-existing cartridges.
