Those 85/2 Nikkors are Leica screw mount. You'll need an M adapter. Most people use the 90mm adapter. The 90mm frame line is "close enough". Should you run into a 50mm f/1.4 Nikkor in Leica mount grab it. Both lenses were better than anything Leitz was making at the time. The 35mm f/1.8 Nikkor, though, wasn't quite up to the standards of the first version 35mm Summicron or the 35mm f/1.8 Canon.
