The 3 x 3" Tiffen 85B ND Filter 3x3" 1-Stopblends both an amber color conversion 85B and a 0.3 neutral density filter. The ND filtration provides a 1-stop exposure reduction for darkening the entire image in order to photograph with a wider aperture or slower shutter speed than normally required. The 85B filtration covers the entire filter plane and converts the color temperature to 3200K for use with type B (tungsten) films.

This filter is made using ColorCore technology, a process that involves laminating the filter substrate between two pieces of optical glass, and grinding flat to a tolerance of 1/10,000th of an inch. This filter measures 3 x 3" / 76.2 x 76.2mm.

0.3 Optical Density    ColorCore Technology    Amber 85B and Neutral Density    Warming Filter to Decrease Color Temp    ND Filter to Increase Exposure Length

Combination of both an amber color conversion 85B and a neutral density filter.

0.3 ND filter darkens the image, allowing you to photograph with a longer shutter speed or wider aperture than normally required.

85B filter converts the color temperature to 3200K, allowing you to use type B tungsten-balanced film in daylight situations.

Q: 8. The spec says Front Filter Thread Size86mm , so can I use a normal 86mm lens cap on the outside of the filter? Thanks!

A: You should be able to use you 77mm lens cap. I do with mine.

Q: 9. What size lens cap fits the Tiffen 82 mm variable ND filter? Thank you!

A: The Tiffen 82mm Variable Neutral Density Filter does not have front filter threads, so standard lens caps are incompatible. The Kaiser 100mm Push-On Lens Cap, BH #KALC100, is a little large. Adding gaffer tape around the inside edge does allow the cap to fit.

Q: 10. Is this compatible with the Moment Cinebloom filter? Can I use both at the same time?

A: While this could be screwed into the front of a Moment 72mm CineBloom filter, there is a chance of vignetting on wide angle lenses.
