Hi folks, First time using the EOS R5 mirrorless (I've rented one for a few days, to "test drive" it before I buy it.). I often shoot live theatre, which usually requires varying degree of brightening in RAW, often by adjusting the "Shadows." While processing some test photos last night, I ran a little test, and toggled the "Shadows" on this photo --- and a very obvious moire pattern appeared. That's never happened to me on a DSLR (5D Mark III or Mark IV). Wondering -- is this just a symptom of the mirrorless camera, or is a user-error that can be fixed? First time shooting mirrorless here, so I'm relying on what always worked well with the 5D. (And I realize, this shot didn't need to have the Shadows adjusted. I was just experimenting.) Thanks!
