Remote Controllers
For remote operation of the DXC-D50 camera, three types of
remote controllers are available, each offering direct control of the
DXC-D50/D50WS camera.
RCP-D50 (Joystick Type)
RCP-D51(Dial Type)
The RCP-D50 and RCP-D51 have been specifically designed for
use with Sony DXC-D50/D50WS cameras. The RCP-D50 is a
joystick-type controller, while the RCP-D51 is a dial-type
controller. Both are equipped with a 3.5-inch* color touch panel
LCD screen and offer extensive control of camera functions
through easy-to-use menu-based operations. The LCD also
allows the incoming camera image to be monitored - a feature
that comes in handy when identifying which RCP is controlling
which camera in multi-camera systems.
Another convenient feature is the Memory Stick system, which
allows various scene files to be stored on and recalled from the
Memory Stick media and loaded to either a different
RCP-D50/D51 controller, or to a DXC-D50 camera.

RM-M7G
The RM-M7G controller is a compact, handheld-type remote
controller ideal for use in the field, or for basic remote control.
*Cannot be used with CCU-TX7/TX7P.
