It is my favorite lens.
It is not much faster than 85/1.8, and it is actually slower focusing (and mine needs "-13" micro-compensation), still for it's purpose it is a true gem.
Bokeh is outstanding (wide open and probably even more so @ f/2-2.2), and the combination of excellent central sharpness, vignetting and lack of sharpness in the corners actually saves you post-processing.
If the AF problem gets more severe, I will just have it fixed and go on using it till one of us passes away. And, unless something happens to it, I guess that won't be 85mm f/1.4.
