Ok, reading the R5 manual I see that CRAW is one of the capture file choices. Knowing nothing about it, I did a google search looking most for any downsides for using. The little that I found said that image quality is not much different from uncompressed RAW and file size is reduced by about 40% on average. If you do a double blind test of the same shot in RAW and CRAW, there are just perceivable differences viewing at 100%, and it would be hard to say which is better. With CFExpress memory cards being so damn expensive, I’m thinking about using CRAW as my primary capture file. Given all the experience available here on the forum I’m asking for any practical knowledge you can share. I am most interested in any image quality degradation you may or may not have seen. Thanks for your help.
