A PL Lens 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 optical converter.
The PL Lens mount (A) includes a 4-pin S4/i data interface. This allows the camera to gather lens metada-
ta from lenses supplied by RED and Cooke Optics, Ltd. using S4/i protocol.
On the left side of the camera body is a RECORD key (B) and two User Keys (C). User Key 1 is pre-
and User Key 2 is pre-assigned to 1:1 FOCUS CHECK. Focus check zooms in the
image to allow for precise focus adjustment. These assignments can be changed in the KEYMAP prefer-
ences menu. Refer to SYSTEM MENU CONTROLS > SET UP > PREFERENCES >
NOTE: If User Key 2 assignment is changed, FOCUS CHECK is still available through the EVF but-
tons. Refer to CAMERA DISPLAYS >
