I don't know about price, but I often shoot entire fashion stories between an 85mm and a 50mm. I prefer the 50 as it's more rewarding to shoot well, but the 85 can create sexy very easy.
I actually got mine cheap with a 28mm 1.4 from a PJ switching to canon. $1200 for both in excellent condition.
I'm very interested in the new Zeiss ZF 85 and 50 too. If for no other reason than their dedicated manual focus design. I can't manually focus my 50 nikkor at all with it's loose barrel. And I feel the price on these is suprisingly reasonable.
