Canon R7 cRAW vs. RAW, any Technical Issues?

[lassevk]

I don't know why, but I was under the impression that Lightroom Classic was unable to handle cRAW, and that I had to use DPP4 to process them, hence I have just configured the camera for RAW and promptly forgot all about it.

Today I tested, and I found that both Lightroom Classic and DxO PureRAW 2 processed the file just fine.

So, given that my own tests, and various articles and Youtube videos all seem to conclude that there isn't a perceivable difference between the two, is there any technical issues with just going for cRAW full time?

Note, I'm specifically *not* asking if you think or feel there is an image quality difference, I'm asking if there is something I won't be able to do, like any particular kind of software that can't use it or whatnot, that should prevent me from using cRAW? Obviously, if you have experienced notable image quality differences I am interested in hearing it, but I'm really just asking if going cRAW would actually be a showstopper in some cases, specifically with software support or similar.

I haven't heard of any compatibility issues attributed to compression of the RAW files.

Only thing I will say is that, in my experience, if you heavily crop and then try to pull detail from the shadows, RAW is better than cRAW. YMMV.

But that scenario is the exception not the rule. At least 90% of the time. Also depends a lot on what camera are you using. A full frame camera will save a lot more details in shadows.

But overall you are right. RAW is better than CRAW which is not a lossless compression.

For me as a wildlife and BIF shooter on an R5 that is more or less the rule.
