I am enclosing two recent shots (small versions) from 50L with ND on 1Ds M3. The lens is very versatile, and delivers when needed. The first shot was captured at f/1.4, whereas the second shot was at f/16. These pictures were slightly enhanced in Aperture (no Photoshop).
Now that I have become a "prime-oholic", I am evaluating 35L against 24L II for landscape photography.
