This 86mm Tiffen 85/ND Filter 86mm 1-Stopblends both an amber color conversion 85 and a 0.3 neutral density filter. The ND filtration provides a 1-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.

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

0.3 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. What is the difference between this lens filter & the Formatt Hitech Ultra version? [Formatt Hitech 77mm Firecrest Ultra ND 0.9 Filter (3-Stop)] Thanks.

A: The Ultra Firecrest series filters exhibit greater clarity and have lower reflectivity than the original Firecrest filters. Borrowing from the range of Firecrest cine filters, the Ultra series filters undergo a secondary lapping and polishing process after the initial polishing and bonding stage. This additional step helps to ensure flatness and consistency for improved image quality.

The abbreviation stands for Columbia Resin #39, because it was the 39th formula of a thermosetting plastic developed by the Columbia Resins project in 1940. It is a common filter material for square and rectangular filters that are used in holders such as the Cokin and Lee holders.
