Description
The RED RANGER Gemini 5K is an all-in-one camera system, built around the Gemini 5K dual-ISO sensor in a single integrated body with production-ready I/O for multi-camera use.
Build and Power
At around 3kg, the RANGER accepts a wide input voltage range (11.5-32V) and includes an advanced cooling system with a larger fan for sustained operation. It offers two 12V and two 24V outputs plus a 12V D-Tap port, and connects to RED’s 24V AC adapter or longer-lasting block batteries via XLR.
I/O and Recording
Three built-in SDI ports cover multi-camera and monitoring setups, alongside genlock, timecode, USB and control ports, and a selectable line/mic/+48V 5-pin XLR audio input. Recording covers REDCODE RAW, Apple ProRes or Avid DNxHR at up to 300MB/s, with RED’s IPP2 HDR colour management. Available in PL mount (default), EF mount or Nikon F mount — select above.
