It must be different. On the new 35/1.4 ASPH, there is an exact angle where
the sun could come through the cut-out and hit the lens surface directly.
The angle, however, couldn't be more than a degree or two. But with a
Heliopan polarizer in place, it moves the front glass surface far enough
forward, that this cannot happen.
