Ahead of the IBC show in Amsterdam, starting next week, Canon has given details of their future upgrades for the Cinema EOS cameras. The C500, C300 and C100 cameras will all see their maximum ISOs pushed from 20,000 to 80,000, with one-stop or 1/3-stop increments from 320ISO all the way up to 80,000ISO. The C500 will gain a new extended colour gamut for digital cinema projection in the form of the DCI-P3+ and a new 4K1K raw setting for a 4096x1080pixel ratio with recording of up to 120fps. The monitoring via the Mon.2 terminal will support up to 2K output and the automatic cooling mode will be update to turn the fan off during recording to reduce noise.
In addition, C300 adds a wide dynamic range option, as seen in the C100, and support for the 18-135mm f/3.5-5.6 IS STM lens including continuous autofocus and enhanced AE. The EOS-1D C also sees an upgrade giving more support for EF lens use, including aperture display and lens metadata.
The upgrades are expected to be released at the end of this year. For more details on the upgrades, see here
