Evening everyone, Here’s a question just because I don’t have the energy tonight to read three large manuals. Camera bodies involved are the D4, 800 and 810. I normally set up to put jpegs on one card and NEF on the other. I was watching a video on a Canon R6 and got the impression that it can write both files to one card and then the other as space is needed. Is that correct? Can the three Nikons I mentioned do this? No need to tell me how, I can figure it out but want to find out if it can be done. Thanks. Rick H.
