Thank God we have Viltrox 50/1.4 and 85/1.4... for the moment anyway, and they have no glaring issues with IQ while their cost isn't prohibitive like that of the Nikon's f/1.2 versions.
There's no Viltrox 35mm f/1.4 (yet?) but they have an f/1.2 that doesn't cost an arm and a leg either. I'm pretty sure they'll have an f/1.4 version too, sooner or later, and it will be even cheaper (as well as more compact). Whether there will be a Z-mount version in another question, given the current litigation between Nikon and Viltrox (and my crystal ball is away for servicing at the moment, so I can't tell you how that plays out in the end). But adapting E-mount lenses is always an option.
