The 150 x 170mm,2-stop Benro Master Series Hard-Edge Reverse-Graduated ND Filter is compatible with filter holders that can accommodate 150mm-wide, 2mm-thick filters. It can be applied to darken bright skies, specifically during a sunrise or sunset, while allowing for a normal, unaffected exposure in the other regions of the image.

This filter achieves its effect with a 0.6 band of density across its center region that provides up to a 2-stop reduction in light from entering a lens. This band extends vertically in both directions and tapers to a band of reduced density toward the edge above it. Directly below the 0.6 band of density, it tapers to clear with a hard-edged line of transition before the clear area.

The placement of a 0.6 band of density with a clear area directly below allows the Benro 150 x 170mm Master Series Hard-Edge Reverse-Graduated Neutral Density 0.6 Filter to match the positioning of the sun when it is at, or immediately above, the horizon. In such instances, the sun can appear closer to the center of an image as opposed to the upper edge, and an increase in brightness is created that is more prominent on both sides of the sun than above it. This pattern of brightness corresponds to the density pattern on the Benro 150 x 170mm Master Series Hard-Edge Reverse-Graduated Neutral Density 0.6 Filter. The hard-edged line of transition in this reverse, graduated neutral density filter is useful for hard transitions between the sky and land, while the gradation above the 0.6 band of density is applicable to multiple regions of brightness within the sky.

Benro Master Series filters are constructed from Schott B270 glass. To prevent internal ghosting and reflections, while further enhancing clarity and color fidelity, each glass surface includes multiple layers of antireflection coatings. These coatings also offer greater protection to the filter substrate and help it to stay clean for longer than with uncoated filters. The nano coating associated with Benro Master Series filters provides an additional 13th layer over each side of this filter, resulting in an improved beading effect when in contact with water for greater cleaning efficiency.

A plastic case with a padded pouch is included for storage and transport.

Q: 1. Does this come with a protective case for the filter?

A: Yes, the B+W MRC Nano Master #803 ND0.9 Filter (82mm) comes with a drawstring filter pouch for protection.

Q: 2. Will this fit the Nisi 75mm filter holder?

A: If the holder works with 75x75mm filters then yes you can use this in it. This should work with any 75x75 Filter Holder.

Q: 3. Does this filter holder produce vignetting when used on wide angle lenses?

A: The manufacture does not list what is the widest lens usable before it vignettes. Averaging this from other brands chances are, it is best not to go more than 20mm or so with a full frame camera.

Q: 4. What is the difference between this and MFR #1089228? Seems like one has a knurled edge and one doesn't - is that it?

A: Both filters are thinner to prevent vignetting on wide angle lenses, but the B+W 67mm MRC Nano Master #806 ND1.8 Filter would offer the knurled edge on the ring as the only difference.

Q: 5. Does the case hold 100x150mm filters?

A: Sorry no. You need this 150mm case. Benro 150mm Master Series Holder and Filter Bag (Black) B&H # BEFB150.

Q: 6. Is the front thread of 82 mm B+W MRC Nano Master #803 ND0.9 Filter still 82 mm? Can I put on a 82 mm CPL in front of this 82 mm ND filter? Thanks

A: Yes, this B+W MRC Nano Master #803 ND0.9 Filter (82mm) does have a front thread.

Q: 7. Is the Benro 100 x 100mm Filter Protecting Frame compatible for use with this version of the Benro filter holder?

A: Benro Master Series 100mm Filter Holder with 95mm Mounting Ring is not compatible with the Benro 100 x 100mm Filter Protecting Frame.

Q: 10. Would this fit the Tilta Mirage?

A: The Benro Master Series 95mm Circular Polarizing Filter for Benro Master Filter Holder would not be compatible with the Tilta Mirage Matte Box as the matte box does not accept screw on filters. The Tilta 95mm Circular Polarizer for Mirage Matte Box, BH #TIMBT16POLA, would be the compatible circular polarizer.
