What's it like using manual focus lenses on the Z6? Pretty good actually. I use to always like shooting manual the most on Fujifilm cameras because they had such nice focus peaking compared to my Sony cameras. But the Z6 has even a bigger advantage over any Sony or Fujifilm cameras that makes it even better. Bigger, and higher quality LCD screens, plus at the time the Nikon Z6 had one of the best EVFs so it's incredibly easy to see what you're doing.
