I love focal lengths from 50 above, sweet spot being 85, I own a few of those but I miss the focal length on Z cameras as the f1.2 which I own is too heavy to take around just for the sake of it.
I own the 85/1.4D and love it, took it for a spin recently and on a D850 it always performs no matter no AI AF assist, unfortunately it can't mount on a Z without loosing AF so I am thorn between getting the S version in f1.8 flavor or if to go for a used G version that I can use on both D and Z body, I would like to know from those who own/owned it how does it perform on native F bayonet and how does it do adapted on a Z body.
G Lenses always adapt quite well to Z - should operate as good as on the DSLR, though with even better focus accuracy.
With that said, there are some third party Z lenses also worth considering - the Sirui Aurora 85mm f/1.4 is fantastic, with an absolutely beautiful rendering and still quite sharp - easily as sharp as either 85G, and it's also rather compact and light. The Viltrox 85mm f/1.4 Pro is also worth a look, with its excellent sharpness and good rendering. The 85/1.8S is a very good lens, but I find it hard to justify its price given the excellent third party glass available at the same price or cheapre. I've owned the 85/1.8S in the past, and I prefer my Aurora 85/1.4 in pretty much every way. I paid $375 used for mine, but even new it's $300 less than the 85S, and I'd prefer it even if they cost the same.
