Canon recently introduced two new file formats: CR3, a new RAW format, and C-RAW which is a new type of compression. Bryan just provided the first assessment of C-RAW that I've seen:

Overall, C-RAW seems to be saving ~40% of space with very little noticeable loss in resolution. I am impressed. I'd be curious if anyone else knows or sees additional descriptions/analysis of CR3 and C-RAW.
