Canon has released a new firmware update for the C70 that adds 4K RAW internal recording at up to 59.94P, as well as a couple of other features.

C70 users can now record 4K RAW internally in Canon’s Cinema RAW Light. You can also record XF-AVC proxies at the same time.

Above you can see what resolutions and frame rates you can record in Canon’s Cinema RAW Light. You have the option of recording 4096 x 2160 in RAW ST or RAW LT. You can only record 4K DCI at 59.94p or 50p in RAW LT. RAW ST is only available in frame rates up to 29.97p.

The data rates are still pretty reasonable for recording in both RAW ST and RAW LT.

You can also record 2048 x 1080 RAW at up to 59.94p in a cropped Super 16mm mode. In this Super 16mm mode, you have the choice of recording RAW HQ, RAW ST, or RAW LT.

You are going to need a reasonably fast SD card to record 4K Cinema RAW Light. A V90 card is required if you want to record internal RAW. I think a lot of people thought that the C70 wouldn’t be able to record RAW internally given the fact that it uses SD media.
