Canon has announced plans to issue a major service upgrade for the Canon EOS-1D C 4K cinema camera. This update will enable Canon EF-mount Cinema lenses to store lens metadata in the video recorded by the camera. Furthermore, Canon EF-mount Cinema lenses will be supported by Peripheral Illumination and Chromatic Aberration Correction functions. Additionally - in response to user requests -, audio on the EOS-1D C camera will also be enhanced. Currently audio recording is limited to a MIC input, but the forthcoming service update will permit selection of LINE or MIC input, allowing use of a wider variety of external audio sources. The update for the Canon EOS-1D C digital SLR cinema camera is scheduled to be available November 2013. Do note that this service upgrade that requires the camera to be sent to an authorised Canon Factory Service Center.
