Ok, I have gone through the R5 manual (have one ordered) to find the answer, but can not.
I know C RAW is compressed so smaller file/MP. I could not find what the MP size is if I use compressed RAW. I know, why buy a 45 MP mirrorless and not use the full 45 available, but there are times when I don’t think I will care. I do some real estate stuff where smaller is just fine.
Question 2, does anyone know if you can set a custom control like C1 to crop and have my settings for wildlife and if for some reason I want to I could just go to C1 and it will go right to crop as opposed to having to go in and change in the menu? I may find cropping the full photo will result in better photos, but if something is far away, maybe the in camera crop will result in a better photo... I guess I will know with practice, but for now just waiting and reading!
Thanks Beth
No loss of MP. The manual doesn’t specify the loss cuz there is no loss to specify.
You’re compressing data, not cropping and not down scaling. Loss will be in dynamic range, not in resolution.
Well just found it finally, 21.9 MP in C RAW
Still have not found the C1 and setting to crop...

You said that C Raw is compressed. Is it also cropped or down scaled ? Are you confusing MP with MB ... pixels vs bytes ? Easy to happen when having the manual but not the actual device.
What you’ve described runs contrary to normal industry practice. Pixel count and compression level are not normally linked.
Q1 - compressed RAW has nothing to do with the pixel resolution of the camera. The compression applies to the file size, as expressed in bytes, not the pixels. At the full 45MP resolution, both the RAW and C-RAW files are 45 'megapixels'.
Q2 - Try registering your own C1 (or C2 or C3) custom functions and confirm whether the 1.6 crop is captured into the custom setting. It should.

Ok, yes I am totally messing up MP vs MB. What MB will they be? I’m just not wanting to fill my computer with large files when I will not really need huge files. When out doing my animals in Africa, I will not compress, but doing other things, times I will not need huge files.

As discussed in this post, you can expect to see C-RAW files that are 45% to 54% smaller than the uncompressed version of the same scene.
https://www.the-digital-picture.com/Canon-Cameras/Canon-C-RAW-Image-File-Format.aspxAs explained in the discussion by Bryan Carnathan, finding a difference between RAW and C-RAW is easiest to find in underexposed (initially darker) images that are then adjusted brighter in processing. But even then, he is unable to say how / if that difference is impactful. Sony uses a lossy compression too. Most people use this setting and never are the wiser.

Thanks for sending the article. I just may have to switch to C-RAW!

I have a couple thoughts for you.
First, for Real Estate stuff or similar stuff where smaller is just fine, why not just shoot those in JPEG unless you need to post process all the real estate photos.
Second, cropping in camera offers no advantages over cropping in post in terms of better photos. However, cropping in post offers you much more flexibility to create a better photo. Once you crop in camera using the "crop" mode you have lost the option to reframe beyond that crop.

Good points, but I do process real estate in post.
From this article and another I have read, I think I will be going CRAW!

As CHG_CANON says, just use CRAW to save space on your computer. Never, never, never choose a smaller file size. You can always go smaller in you post processing, but it's difficult to go larger. Not impossible, but difficult. I've read some reviews about CRAW and you can't see any difference at all with the new R5 camera, between the RAW and CRAW.....

Craw is not cropping, just file compression.
