Canon C400: 6K Full Frame RF Mount Cinema Camera

Canon has just announced the EOS C400, a new 6K full frame RF mount cinema camera with three base ISOs. The C400 is a similar to a smaller C500 that can record internally in 6K at up to 60p in Cinema RAW Lite as well as 4K up to 120p in XF-AVC 4:2:2 10-Bit.

We're pretty excited about this new full frame offering from Canon and you can get in touch with us now to secure your pre-order


The C400 is based around a brand new 6K full frame Back Illuminated Stacked sensor that is a first for Cinema EOS cameras. 

Canon claims that the C400 has 16 stops of dynamic range. This claimed figure is 1 stop more than the C500 Mark II and on par with the C300 Mark III which utilizes a DGO sensor.


Canon has gone one better than many cameras on the market with dual native ISOs, by giving the C400 three native ISOs. Which will add flexibility between low and high base sensitivities.  

On the C400 you can manually choose between three native ISOs or you can put it in to an Auto mode.

The three native ISOs vary depending on what shooting mode you are in.

Canon has made their own proprietary PL-RF Adapter for the C400.

It can be user installed on the camera using four M3 bolts and locking plates that attach to the front of the camera.

The adapter, unlike other third-party solutions on the market has electronic connections and it can utilize the Cooke /i protocol to send compatible lens information to the camera.


An improved Dual Pixel CMOS AF II system features 1053 automatic AF points, which cover the entire sensor area, for faster and more precise auto focusing performance. 


The C400 features a single CFexpress Type B card slot as well as an SD card slot which you can use to record low-resolution proxies and some of the non Cinema RAW Lite codecs.  

You can record XF-AVC, XF-HEVC S (H.265) or XF-AVC S (H.264) to the SD card slot. Cinema RAW Lite can only be recorded to a CFexpress Type B card.
