This Formatt Hitech 82mm Filter Holder Adapter Ring allows the filter holder included with a 100mm Firecrest Filter Holder Kit to be used on a lens with 82mm front filter threads. It features an aluminum-alloy construction for durability while remaining lightweight.
This adapter ring accommodates the Formatt Hitech 82mm Firecrest UltraSlim Circular Polarizer Filter that is included with a 100mm Firecrest Filter Holder Kit. When combined with this adapter ring installed on a lens with 82mm front filter threads, or adapted to lenses with other front filter thread diameters, that polarizer filter can be rotated to adjust its effect. The combination of the circular polarizer and this adapter ring, plus an optional step-up ring, can also be used with the filter holder with or without its included cover installed. In such instances, an external dial on the filter holder allows for the independent rotation of the circular polarizer.
Alternatively, separately available 72mm or 77mm filter holder adapter rings for the 100mm Firecrest Filter Holder Kit accommodate the circular polarizer as well. They provide the ability to mount the filter holder onto a lens with 72mm or 77mm front filter threads without the need for this 82mm adapter ring and an additional step-up ring. When the filter holder is used on a wide-angle lens with 72mm or 77mm front filter threads, those adapter rings can help prevent vignetting.
Included with a 100mm Firecrest Filter Holder Kit, multiple step-up rings allow a Formatt Hitech 82mm Filter Holder Adapter Ring to be used with lenses that have 67mm, 72mm, or 77mm front filter threads; additional step-up rings are also available for lenses with 46mm, 52mm, 58mm, or 62mm front filter threads.
