Beautiful lens! the choice to replace the 20-35mm; I have not used the 17-35mm, so I can't compare with the top wide angle zoom. In fact, the 20-35mm is already very "West Germany" feeling, the 16-35mm is pushing much higher, plus the flare control in incrediable.

This is a shoot taken after a photo shooting job in Yuen Long, this is the first time I use it. I found it is very special lens, it is better than any lens that I have used; in which, those 120 format lens are included. It is very good. The very contrast & extreme skylight are well present the lens advantages. We can watch the details on the tree, and the sky on the diagonal. This photo had not been processed any parameters.
