3. Physical Controls
This section describes the physical controls 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; and with B4 lenses via
the optional B4 to PL converter. The PL mount may include an S4/i interface. If installed, this
interface permits the camera to communicate with various lenses from RED Digital Cinema,
Cooke Optics. Ltd and other lens manufacturers supporting the S4/i protocols.
On the left side of the camera body are a RECORD key and two User Keys. The two User Keys
are pre-assigned to AUTO WB and FOCUS checks functions. If desired, these keys may be dis-
abled in the SYSTEM / KEYMAP sub menu to prevent accidental use.
An SD Memory card slot is provided below this group of keys, and may be used for camera
setup storage and software upgrades. A blank 512MB SD card is provided with the camera.
