I've been using the 85mm f/1.8D for almost a year now, and took a step out to get the f/1.4D version, and was not disappointed!  The 85mm f/1.4D lens is the cream machine when it comes to bokeh.  At almost every f-stop, the bokehs still come out rounded, but for the 85mm f/1.8D lens, there are certain f-stops where it is not rounded, but can see the polygonal shape from the aperture blades.  The f/1.4D lens is almost 3 times the price of the f/1.8D lens, but the built and performace is also better.

This lens is already pretty sharp wide open, but stopping down to f/2, you can see that it gets sharper.  The only thing which I do not like in this lens package (and is the same for the 85mm f/1.8D lens package too) is the screw on lens hood to the filter thread.  In anycase, shooting without a lens hood is not a problem.
