Canon has rolled out new firmware updates for its Cinema EOS lineup, including the EOS R5 C, EOS C50, EOS C70, EOS C80, and EOS C400. These updates introduce major new features such as Cinema Exposure mode, expanded Cine Servo lens compatibility, external audio output in Slow & Fast Motion, and multiple workflow refinements.
Canon EOS C80 & C400 Firmware v1.0.7.1 – Cinema Exposure Arrives
The headline addition for the EOS C80 and EOS C400 is the new Cinema Exposure mode. This feature adjusts dynamic range allocation between highlights and shadows according to ISO sensitivity, improving highlight performance above base ISO. For filmmakers working in uncontrolled lighting, this is a significant enhancement.
Both cameras also gain support for Canon’s CN30×40 IAS J/R1 RF‑mount and CN30×40 IAS J/P1 PL‑mount Cine Servo lenses. The EOS C400 adds Auto Exposure Ramping Compensation, maintaining consistent brightness during long zooms with compatible Cine Servo lenses. External audio output during Slow & Fast Motion recording is now supported via SDI, HDMI, or headphones.
