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.
The Kipon IBERIT 35mm f2.4 is a lightweight compact full-frame 35mm f2.4 mirrorless lens. It's constructed of an aluminum body with a brass and stainless steel core for a low weight design. While the Handevision 35mm f2.4 is not a very fast lens, its characteristics are very balanced with a classic style of rendering and an extremely versatile 35mm focal length.
