The 4 x 6" Tiffen 85B ND Filter 4x6" - 4 Stopblends both an amber color conversion 85B and a 1.2 neutral density filter. The ND filtration provides a 4-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 4 x 6" / 101.6 x 152.4mm.

1.2 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.

1.2 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: 6. If I’m shooting an eclipse event but not the sun/moon directly—just people—is this filter still needed to protect my gear?

A: This Solar Filter is used when you're shooting directly at the sun during the eclipse. This would be too dark to use for normal photography.

Q: 7. Is it safe to use this filter with a tracked 700mm lens on a Canon EOS R for the duration of the eclipse (~3 hr)?

A: Yes, the Tiffen Solar ND Filter is designed to be used for Solar Eclipses and other solar phenomenons.

Q: 8. 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. On a Tamron 18-300 for Fuji (crop), will this have vignetting at 18mm? If so, what thread should I move up to (stock is 67mm)?

A: The Tiffen 67mm Variable Neutral Density Filter will not vignette the image on the Tamron 18-300mm lens. I would recommend considering the 77mm version (and a 67 to 77mm step up ring) because that would allow use on more lenses.
