I would recomment the AF-S 85mm f1.8 if it really has to be a 85mm. Otherwise I always recomment the Tokina 100mm f2.8 macro because its cheap, well built, and optically absolutely awesome. P.s.: Needs a screwdrive motor though for autofocus, OP doesnt say what camera she uses, so no idea. P.p.s.: I myself use of course Nikons Bokeh lens, the AF 105mm f2 DC. P.p.p.s.: Oh, I see the OP is using the Df. Then thats fine.
