This 77mm Tiffen 85/ND 2-Stop Filter 77mmblends both an amber color conversion 85 and a 0.6 neutral density filter. The ND filtration provides a 2-stop exposure reduction for darkening the entire image in order to photograph with a wider aperture or slower shutter speed than normally required. The 85 filtration covers the entire filter plane and converts the color temperature to 3400K for use with type A (tungsten) film.

This filter is made using ColorCore technology, a process that involves laminating the filter substrate between 2 pieces of optical glass, grinding flat to a tolerance of 1/10,000th of an inch, and then mounting to precision metal rings.

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

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

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

85 filter converts the color temperature to 3400K, allowing you to use type A tungsten-balanced film in daylight situations.

Q: 1. Can I mount this on top of a circular polarizing filter? Is there a downside to doing that?

A: The Tiffen VND filter consists of two circular polarizing filters...two CP filters together create the VND effect. Mounting this on top of a circular polarizing filter may cause some undersired effects such as cross polarization, vignetting in addition to difficulty adjusting the two filters as both turn and are adjusted by hand... if you mount the CP, then the VND it would be difficult to control both as they are turning. We recommend using a straight ND and then a CP instead.

Q: 2. Can anyone tell me what the dot markings represent in amount of stops of light being reduced? Is the min setting 2 stops immediately and what does each progressive dot on the scale represent in stops of light reduced? Are they fractions of stops or whole stops? (I assume 'max' equals 8 stops of light reduced) Thanks for any feedback in advance!

A: Justin... the dots on the filter ring are just reference points and do not relate to actual stop values. At the MIN setting you are at 2 stops, at the MAX setting you are at 8 stops. Between those two points there is no way to determine the exact stop value. If you need to know the exact stop value we also manufacture solid ND filters in a variety of stop values.

Q: 3. I have the Sony Zeiss 24-70mm F4. It says on the Lens 67mm. Does that mean I need a size 67mm ND Filter to fit?

A: Well as others have indicated, 67 mm is the correct size for the lens, you are asking about. while this is true, some times it is more cost efficient to get a larger size filter and an adaptor ring. When buying my natural density filter, I chose one that fit on the largest diamiter lens in my travel kit, so that I could use the filter on all my lenses, with the only added cost/weight of the adaptors. This also alows for a larger filter to be used on my wider angle lenses, reducing any vignetting that the filter might cause on the wide angle lenses. Vignetting can be a problem on wide angle lenses as the Variable Neutral Density Filter tends to be fairly thick and there for may caused some vignetting.

Q: 4. Does the 52mm fit on my 18-55mm Nikon D5600 lens?

A: You can use the lens to filter size tool on the Tiffen website to determine this information: https://tiffen.com/pages/filter-collection

Q: 5. Whats the outer diameter for the 82mm VND?

A: Tiffen 82mm Variable Neutral Density Filter has a 98mm outer diameter.

Q: 6. Considering this filter for the Sigma 50-100mm f/1.8 DC HSM Art lens, so vignetting should not be an issue for a telephoto. However, lack of front threads or provision for a lens hood is an issue. Is there a solution?

A: Hey Danny I haven't found a solution for a good, but never look hard after a solution either. I use it with my L series zooms and I can't never use lens hood with it. It is one of the smallest nd out there but still not small enough. Hope it helps

Q: 7. Does this filter work on a sony 70-200mm lens?

A: It depends which Sony 70-200 it is. If it is Sony FE 70-200mm f/2.8 GM OSS II Lens then Tiffen 77mm Variable Neutral Density Filter will work because that lens does accept 77mm filters.

Q: 8. I have a Canon MIII. Will this Tiffen 77VND work with a 50mm lens?

A: Whether this filter will fit your lens depends on the exact 50mm lens. The front diameter of the lens is generally printed on the front or stamped behind the lens cap.

Q: 9. Is there a way to make them fit in the Rokinon lenses? I heard Rokinon lenses doesn't have a way to add filters.

A: All Tiffen screw in filters require filter threads. We make the VND filter in 52, 58, 62, 67, 72, 77 and 82 mm sizes. We recommend you contact Rokinon for specifications regarding their lenses

Q: 10. Whats the filter size for the outside thread?

A: The Tiffen Variable ND Filters do not have front threads for attaching other lens accessories like a lens cap or screw on lens hood.
