Yeah that's exactly what happens. The 85mm 1.8G is really good enough though! I wouldn't want to fudge with focus screens - I managed to cock up a D750 doing that once. Took ages to get it right after.
Really I stopped shooting film in 2022 because of the arrival of CT scanners at airports. Fed up of arguing with people as I do most of my photography out of my home country. And it's expensive. Sold it all, bought a Nikon Z50ii basic kit in 2024 and that was so good and tiny that I sold my D850 and the rest of the F mount lenses. AF on the newer Z cameras is something special, even on the crap bodies. Haven't felt the need to buy an FX Z yet as the DX ones are so good.
