You've already got the Tamron 90/2.8. So I don't see the value of the expensive Nikon 85/1.4 for two stops more light.
I was going to say that you should investigate the Samyang series, but I see that you have. I love their lenses, owning the 85/1.4, 35/1.4 and the 14/2.8 -- all for well under $1000. They are also supposed to come out soon with a 24/1.4, and I'll be in line for that.
I also like the Zeiss idea. But you prefer AF, and I can understand that.
In your position, I'd look for another versatile zoom lens, like the 24-70/2.8, or maybe the 24/120/4 (although the 24-70 gets mostly better reviews). Then maybe you would think about filling in with one of those fast Samyang?
I'm sure you'll have fun deciding!
galenapass -- I haven't had any trouble focusing my Samyang 85/1.4 on FF or APS-H body's OVF. Crop sensor OVF are very tough for me, using MF lenses.
