Hello, I'm looking to do more in-depth information about the EOS R5 C . I'm going to be exploring shooting 6K RAW S35 (I think it is 1.38 crop). I want to know if the Dynamic range is any different in 6K than 8K RAW? I see the this camera is rated to 15 stops of dynamic range as a whole, but I'm thinking that is from the full width of the sensor (DCI). If I crop in to S35 mode what are the differences in specs. I could be looking at this all wrong but wanted to find out.
How many Megapixels in the S35 Mode as oppose tot he 45 in Full Frame?
What is the difference in dynamic range?
Thank you for your time and help in advance.

This is an interesting topic.
The R5 C was initially capable of 13 stops of DR before it received Netflix certification. That came with FW 1.0.3.1. Then it went to 14+ stops. I guess we can look at your question this way. Lowering the capture resolution on the R5 C does not decrease DR (8k, Super 35, Super 16). However, the recording format and framerate you choose affects the capture bitrate in a given resolution which in turn affects the available DR in that recording mode. You need to shoot at base ISO 800 or lower to get the maximum DR from the sensor in any mode.
I think much of the information you are looking for is available in the Cinema OS User Guide:
Here is some additional info for you:

• Image Sensor
Full frame CMOS sensor
Effective pixels (approximate, with [Full Frame] sensor mode):
35,400,000 pixels (8192x4320) when the resolution is 8192×4320 / 4096×2160 / 2048×1080
33,200,000 pixels (7680×4320) when the resolution is 7680×4320 / 3840×2160 / 1920×1080
Effective pixels (approximate, with [Super 35mm (Cropped)] sensor mode):
18,700,000 pixels (5952×3140) when the resolution is 5952×3140 / 4096×2160 / 2048×1080
17,500,000 pixels (5580×3140) when the resolution is 3840×2160 / 1920×1080
Effective pixels (approximate, with [Super 16mm (Cropped)] sensor mode):
4,700,000 pixels (2976×1570) when the resolution is 2976×1570 / 2048×1080
4,400,000 pixels (2790×1570) when the resolution is 1920×1080 / 1280×720
• Approximate lens multiplication factor (for 35mm equivalent focal length)
[Super 35mm (Cropped)] sensor mode:
1.460 when the horizontal resolution is 5952/4096/2048
1.534 when the horizontal resolution is 3840/1920/1280
[Super 16mm (Cropped)] sensor mode:
2.920 when the horizontal resolution is 2976/2048
3.069 when the horizontal resolution is 1920/1280
I do really like my R5 C. I am not a cinematographer and shoot video as a hobby.

Let me ping my colleague Rick he is an EOS R5C owner.

Wow, this is great information, thank you!! I shot a project with Canon EF 85mm f/1.2 L lens 8K RAW 60fps and was unhappy with the result. I think my problem was the lens. Not too convinced that the lens can resolve 8K and the high resolution and high megapixels tells on the weakness of the lens. On the same project I shot on the Nikon Z6III using Canon EF 24 - 70mm f/2.8 II L and it did better despite being a 24MP sensor. The lenses was the difference in this project. I'm thinking about trying to shoot the R5C in S35 to bring down the MP to see what the results would be in 6K RAW. Need to do more tests to see how things fair. I believe the R5C is a superior camera but needs better glass that can resolve 8K if I plan on shooting this high of a resolution.

I and others here will be interested in your results so please feel free to post again.
