I use the Zeiss APO Sonnar 135 on a D810A and the stars are perfect all the way to the corner wide open. Examples here:

The only comparable lens I've used that comes close is the old Nikkor 180 D f2.8 that is almost as good - and lets you autofocus. I also use the 135mm for daytime and couldn't care less about the AF, - for the kind of shooting I do I can watch for the little green dot when I'm focusing manually. A stunning lens that is so well constructed it could survive being arrested in Victoria.
cheers,
Andrew.
