I will start this simple comparison off by explaining that this is my opinion and my opinion ONLY. The features we are comparing are the features that were important to OUR company while choosing our next camera, which did end up being the Scarlet. I am sure their are many people who feel the C300 is being underrated, I personally believe that this camera is too little, too late and waaaay too expensive for what it is. Had the C300 been priced to compete against the Panasonic AF100 and the Sony FS100 the results would have been much different, but instead Canon attempted to play ball with the big boys and IMHO lost.
Simple Comparison: Red Scarlet-X VS Canon C300
Canon C300: Canon XF Codec - 4:2:2 50 Mb/s MPEG-2
Red Scarlet-X: 16bit Redcode RAW **WINNER**
Max Video Resolution:
Canon C300: 1080p HD (1920x1080)
Red Scarlet: 4k Cinema Standard (4096x2160) **WINNER**
Canon C300: s35
Red Scarlet-X: s35
Canon C300: 12 Stops
Red Scarlet-X: 13.5 Stops (18 Stops w/HDRx On) **WINNER**
Low Light Performance:
Canon C300: "Usable" up to 16,000 ISO **WINNER**
Red Scarlet-X: "Usable" up to 1600 ISO
Actual Retail Price:
Canon C300: $15,999 (THROUGH B&H)
Red Scarlet-X: $15,965 (WITH PRICE INCREASE) **WINNER**
One issue worth noting for the Canon C300 is the capacity and pricing of it's recording media. It is much cheaper to record an hour of C300 footage to Compact Flash than it is to record an hour of 16 bit REDRAW 4k 8:1 footage to a Red SSD. However, because of the vast difference in codec quality and resolution that would be like comparing apples to oranges.
WINNER: Red Scarlet-X
Better luck next time Canon...
