Before getting my 5DII, I used the 85mm f/1.2L II on my 7D for portraits - despite the relatively slow AF, I think it's great for that use. I had the 85mm f/1.8 previously, and the L version delivers better bokeh as well as shallower DoF. I liked the framing and DoF of the 85L on the 7D so well, that after getting the 5DII, I also got the 135mm f/2L, since that is the FF-equivalent of the 85L on APS-C.

Since you're using a 7D, here are a few examples:


EOS 7D, EF 85mm f/1.2L II USM, 1/1250 s, f/1.4, ISO 100


EOS 7D, EF 85mm f/1.2L II USM, 1/2000 s, f/1.6, ISO 100
