Arca-Swiss Rm3d Fac Unit
Fac system for Rm3di.
The Fac is the frame of the factum, without the helical ramp that carries the lens (called Tum and common to the Rl3di and Rm3di).
The rocking mechanism allows horizontal and vertical movements of +/-15mm; the incline is +/-5°
The purchase of the Fac allows the owners of Rm3di or Rl3D to have a factum, a very light camera, in addition to their usual device.
