The Lux is sharper (wide open) at distance than at close range which is kind of ironic for a 'portrait lens. It's actually quite sharp wide open around the centre but sharpness drops off a fair bit at the edges at any distance. And then there's the glow (SA), which is nice in a portrait but possibly not so nice in general use. I think it is a great portrait lens as a result.

And with my copy, I found it was sharper in the center than my 85LII when both were shot at f/2. By f/2.8, it was razor sharp across the frame.
Although I've never compared the Lux to the 85LII I found the same results as yours with the FD 85 SSC Asph. and the 85L(I). The Canon 85's are sharpest wide open but this advantages is gone just one stop down so is it worth it unless you always shoot wide open?
