It's all about how much you have to spend. Money no object, then the 85mm 1.4 is a no - brainer, followed close by the 105mm 1.8. If you are on a budget, go for the 105mm 2.5, a truly great lens, especially the older single coated ones. The 123mm 2.8 is also very nice, available cheaply these days as 135 has fallen from favour a bit. The only problem with this lens is the size and weight.
