This 72mm Tiffen 85B ND Filter 72mm 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.

Related Questions and Answers

Q: 1. Can/Should this be used in conjunction with a UV filter?

A: We recommend always having a Tiffen UV filter on your lens. The Tiffen VND can attach to the outside filter threads on the UV filter, however when shooting at wide angle you may experience vignetting. If so, you will have to remove the UV filter and just shoot with the VND.

Q: 2. 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: 3. I have the Sony FE 70-200mm F4. What size do i need to fit this ND FIlter?

A: You can answer your question, by looking at the threaded, filter end of your Sony lens, where the correct size should be printed on the bezel. Good luck!

Q: 4. I purchased a 77mm Tiffen Variable ND Filter from you recently--can I get an adapter to adapt this to my Olympus 40-150mm Pro f2.8 lens? Also, is there any problem adapting ND Filters?

A: Without checking, I'm pretty sure you can get an adapter here from B&H. There should be no problem since your 77mm is larger than the 72 mm size of the Olympus lens B&H Shows it to be. Sometimes there is a problem with the filter causing light drop off around the edges but I would think you should be OK with a normal adapter, but you could also see if they have a thin adapter specially designed to minimize that problem in wide angle lenses where it is more prevalent (those in the 24-70 range), etc., but at 40 mm, I'm thinking you wouldn't have a problem either way!

Q: 5. Can this filter be used with a lens hood?

A: I have the filter for my Canon 70-200 and NO, the lens hood cannot physically fit over the filter.

Q: 6. can i mount a rubber lens hood on the front ?

A: Yes...the 67mm version has 77mm threads on the front so you could mount a threaded lens hood.

Q: 7. If I have a sigma 18-35 f/1.8 will I still be able to attach a lens hood to the front with this ND filter on?

A: Noah... the Tiffen VND filter ring is larger than the diameter of your lens. This is done to prevent vignetting in images. Unfortunately, it will not allow a lens hood to attach.

Q: 8. I own a Sigma 10-20mm f/3.5 super wide-angle lense, will this filter cause any vignetting? I'm worried that with the 102.4 degree view that it will still catch the rim in my shots and I don't want to spend $160.00 on something I won't be happy with.

A: The Tiffen VND will vignette at approximately 24mm on a full frame camera and 16mm on a cropped sensor camera. Your choice depends on which camera you have and if you wish to live with some vignetting at wider angles when shooting with a cropped sensor camera.

Q: 9. Has anybody tried this filter on an Panasonic FZ300, or for that matter FZ200?

A: Coenraad, thanks for your interest in the Tiffen VND filter. The X Bar effect you mentioned is a product of optical physics and happens with all VND filters when operated outside their intended parameters. VND filters consist of two polarizing filters, as you twist one polarizer in relation to another you create the VND effect. The X Bar typically happens when you are shooting the filter at darker densities and you are using a wide focal length, this will be more common on full frame sensor cameras instead of cropped sensor cameras. To eliminate the X Bar effect you should reduce the density setting of the VND, change your focal length by zooming on more or a combination of both until the effect disappears.

Q: 10. How to photograph lights at night to get the starburst look

A: The Tiffen 77mm Variable Neutral Density Filter is usually used to slow down the shutter speed or when using a wider aperture. For a star burst effect at night, a filter such as the Tiffen 77mm North Star Effect Filter is often used: https://bhpho.to/4cTxgSe.
