Andrew, thanks for the post.
With your background, I am curious about your thoughts on the 135's. 2.0 vs. 2.5 vs. 2.8 vs. 3.5.
Also curious what you think of the 55mm f/1.2 S.S.C. (not Aspheric model). It is one of my favorites regardless, but I would like to hear what you have got to say about it on a technical level, especially in comparison to the other f/1.2 offerings.
