This 6 x 6" Tiffen Combination 81EF/ND Filter blends both an amber light-balancing 81EF and a 0.9 neutral density filter. The ND filtration provides a 3-stop exposure reduction for darkening the entire image in order to photograph with a wider aperture or slower shutter speed than normally required. The 81EF filtration covers the entire filter plane and lessens the color temperature by 650K, enabling the ability to attain 3200K balance when the prevailing light source is 3850K.

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 6 x 6" / 152.4 x 152.4mm.

Combination of both an amber light-balancing 81EF and an ND filter.

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

81EF light-balancing filter decreases color temperature and provides a warming effect.

Q: 1. 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.

Q: 2. 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.

Q: 3. Does this also work as a clear UV filter?

A: ND filter is used to reduce the light while UV filter is used to block the UV light

Q: 4. 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: 5. Could you recommend a lens cap for this filter please? The filter is 82mm but the front part of (I think) 94mm.

A: You may have success with the Kaiser 85mm Push-On (http://bhpho.to/2aJYEnM). People seem to have luck with other 82mm sized filters.

Q: 6. I purchased this filter a few days ago. What lens cap fits this filter?. I have been told that a 82 mm cap fits as the out flange is 82MM to avoid vignetting

A: Tiffen VND filters do not have filter threads on the front side to avoid vignetting. For this reason, standard lens caps will not fit. We recommend slip on lens caps instead, or simply remove the filter and return it to it's protective pouch.

Q: 7. Is there a trick for screwing the filter onto the lens and getting the white dot on the top in the middle, so easy to see Min/Max?

A: That is not possible, the dot falls where it may when screwed to a lens.

Q: 8. does the Tiffen 52mm fader have front threads? the product photo doesn't show any, and I read a review stating there were no front threads---I realize the specs indicate it has the threads---just want to be surethank you
