An array of small lenses distributed within the surface of this filter smooths fine lines and textures, which can be useful for creating a more flattering result of a subject.

This filter has a grade of 4. Grades of 1/8, 1/4, 1/2, 1, 2, 3, and 5 are also available where this filter type's effect becomes approximately twice as strong with each grade number increase. When higher grade numbers are applied, a halation effect around highlights can be created to further enhance a subject's appearance or produce a desired effect.

This filter is constructed from optical glass for clarity as well as color fidelity and is compatible with filter holders that can accommodate 4mm-thick, 5 x 5" rectangular filters. It 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.

Q: 7. 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.
