I have used both the 35/2.0 aspherical and 35/2.0 non asperherical. At f2.0
the 35/2.0 is really sharp and the contrast is very good. The 35/2.0 non,
is a little bit soft on the edge, but very minimal. However at f4-5.6, I
can hardly tell the difference between the two.

Conclusion: if u like to use f2.0 at alot, the aspherical has a slight
advantage, but if u stop down a lot, then no difference it makes.
