This 77mm Tiffen 85B ND Filter 77mm - 3 Stopblends both an amber color conversion 85B 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 85B filtration covers the entire filter plane and converts the color temperature to 3200K for use with type B (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.

0.9 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.

0.9 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: 1. Normal 85b is reduced by 0.6 stops. This is normal 85b(0.6) + nd(0.3) product?? Or does the new technology mean that the 85b filter itself only reduces 0.3 stops?

A: No, the following filter blends both an amber color conversion 85B and a 0.3 neutral density filter.

Q: 2. Hi I use 5D markiii ,I bought this ND, it only can shoot nature , it shoot people pics too?thanks

A: The TIffen VND filter provides you with 2 to 8 stops of light control. You can use this to limit the light entering your lens/camera in order to do long exposures during the day, or you can use it to limit light entering your camera during the bright sun in order to shoot low apertures for a shallow depth of field.

Q: 3. 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: 4. Whats the outer diameter for the 82mm VND?

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

Q: 5. 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.

Q: 6. I want to achieve vivid, saturated colors in scenes with lots of natural light. Will this filter help me with that?

A: The use of hte Tiffen 82mm Variable Neutral Density Filter is to reduce the amount of light getting to through the lens. Many use this to shoot wide open and or at a very slow shutter speed. It is not made to increase saturation.

Q: 7. 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: 8. without front threads, what lens cap can I use this filter?

A: I suggest using one of the Op/Tech Hood Hats as a cover: http://bhpho.to/1w9ZAZT

Q: 9. How many stops will this filter give me compared to the 58CP filter?"

A: This Tiffen 72mm Variable Neutral Density Filter can reduce exposure from between 2 stops to 8 stops; the Tiffen 58mm Circular Polarizing Filter will reduce exposure about 1.2 stops.

Q: 10. 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.
