    Getting either a 6 or 10 stop B+W ND filter and I was wondering if this thing required a slim mount filter or not?

    I always used the slim version of the B+W UV filter (XS-PRO) - an additional advantage is that those filters come with a push-on lens cap which I found much more practical than the OE article. I do remember a bit of vignetting sometimes around the 9mm end when I tried to use "normal" filters.

    I've never had a slim filter before, is it more expensive usually?

    I have a marumi super high grade CPL and no problems. I can't imagine an ND filter thicker than a normal CPL. 18mm ain't that wide
  5. An alternative would be to use a step up ring to a much larger filter size. I step all my filters to 77mm (and 60mm to a lesser extent). Allows the use of the same set of filters for all my lenses of all sorts of different thread sizes.

    I have a 12mm (full 135 frame lens) on another camera that came with a step up filter attachment to 77mm.

    PS> Don't use CPL on ultra wide lenses.... you get un-uniform polarization across the frame.

    Mine usually has a bog-standard Hoya SHMC UV on it, and no vignetting at all. Usayit's advice is spot on if there is sky in your pictures.
