D850 is indeed very good but you have done well to get a 5D4. I also like my 5D4 a lot! As an analog EOS user with many Canon lenses I too entered the digital world with a Canon DSLR (and other Canon DSLRs followed suit!).D850 is sweet. Gave it a hard look when I was shopping 5D4. The giant pile of glass behind me kept me in place.
