Manuel: I have no problems with the BW ND 110 and the 16-35. There is some vignetting @16mm but most of the time this does not bother me, depending on the motif i go to 18mm. I think i have posted lot\'s of pics with that combination.
Thanks Werner... In fact, I bought B+W instead Hoya after seeing all your wonderful pictures In my copy, I noticed also a strong color cast (brown)
Michiel, fantastic panorama... very nice composition and colors
