3. Physical Controls and Connectors
This section describes the physical controls and connectors on the RED ONE™ camera body.
A. PL Lens Mount B. Record C. User Keys 1 and 2
A PL mount is provided as standard with the RED ONE™ camera. The mount is compatible
with the majority of S35mm, 35mm and S16mm cinematography lenses. In addition, broadcast
B4 mount lenses may be used if the camera is equipped with the optional B4 to PL mount op-
tical converter.
The PL mount includes a 4-pin S4/i data interface. This allows the camera to gather lens meta-
data from lenses supplied by RED and Cooke Optics. Ltd, using the S4/i protocol.
On the left side of the camera body are a RECORD key and two User Keys. User Key 1 is pre-
assigned to AUTO WB and User Key 2 is pre-assigned to 1:1 FOCUS CHECK, however these
assignments can be changed in the KEYMAP preferences menu.
A SD Memory Card slot is located below this group of keys, which supports most SD Cards of
up to 1GB capacity. It is not possible to store video or audio data to the card SD card, however it
may be used for camera firmware upgrades and to store USER PROFILE and LOOK files.
