I'll probably have an A85/1.4 at GFM if you are coming.... The M85/2 has a 5 blade diaphragm, which can make the bokeh a bit harsh at mid apertures, but with careful sharpening, it stays quite nice. The problems are when you have a background that is out of focus, but not so out of focus that USM ignores it. Then you get a really ugly (and completely avoidable) double image bokeh.
