I have several of the lenses you mention and the D800...the 50mm f/1.8 is OK. The 24-50 and the 35-135 will disappoint. If you are cash limited for lenses, I'd keep the 50mm and sell the rest. For inexpensive (but better) lenses in the mean time, I'd pick up a used 28-105 and a 24 f/2.8. If you really need something out to 200mm, try to pick up the constant aperture 70-210 f/4 until you can upgrade. I think you'll come out no worse than cash even on my suggestions after selling off the others. So, then if you have a few $$ beyond that, the 85mm f/1.8 is a very good choice.
