B+W 52mm 502 Graduated ND Gray Filter F-PRO * NEW

Because it attenuates the light twice as much as the previous filter, i.e. by two aperture stops (it transmits 25% of the incoming light), this graduated filter already produces quite dramatic effects.  Because of the increased difference in brightness, it is even more important for the horizon line not to be positioned too far from the center of the image.

Often it is necessary or desirable to balance the light intensity in one part of a scene with another. This is especially true in situations where you don't have total light control, as in bright contrasty landscapes. Fabricated from high-quality CR-39 acrylic, B&W graduated neutral density filters are gray toned in one half of the filter and are smoothly graduated into the clear portion. B&W Graduated Neutral Density filters are available in 2 grades; #501 (approx. 1 stop density at the top) and #502 (approx. 2 stops density at the top).

The mounts of graduated Filters can be rotated, so that the line of transition between the colored and the clear half of the filter can be adjusted in relation to the subject without appearing unnatural.

Compared to the earlier B+W standard mount, The B+W Standard Filter Mount F-Pro has been improved considerably.  While maintaining the excellent quality of materials, fabrication, and high mechanical stability, the new F-Pro mount has become thinner, so that now it can also be used on many wide-angle lenses without the danger of vignetting.  Another advantage of the new F-Pro filter mount is its modified retaining ring, which is no longer threaded in from the front, but holds the filter glass in place from the back.  This prevents the retaining ring from being accidentally loosened during the removal of an additional filter or a lens hood that has been screwed in too tightly.
