I have not used the 35mm ASPH, but I have used the pre-ASPH Lux, and I agree with the previous posters that the lens tends to get a bad rap on forums on the internet. I have tried to shoot mine under flary conditions and it has behaved well. I find it sharp enough for my purposes, although i rarely need to use it wide open. It is VERY SMALL, and that was it's main attraction to me. It has nice bokeh in my opinion, and the results fromit are not clinically sterile feeling.
So, I'm happy with it. I see it as a good f/2.8 lens, with the more wide stops as options if the light level really requires them. Nice to have. I don't have very many scans from this lens right now, but will try to post some at some point later.
