Introducing FireCrest Ultra-Cinny Super Slim IRND filters. They are the lightest possible 4x5.65 cinema grade glass filters with a thickness of 2 millimeters, weighing in at half the weight of a 4 millimeter filter. They maintain the same excellent neutrality and optical quality of the world-renowned FireCrest filters. These Super Slim filters are available in 4x5.65. Each filter is also water and scratch-resistant. The Super Slim filters are supported by a custom high-quality aluminum 4x5.65 2 millimeter Super Slim tray, allowing use in any brand-mat box that uses an RE standard width tray. The 2 millimeter Super Slim tray does not accept standard 4 millimeter thick cinema filters. You can, however, stack two of the Super Slim filters into one traditional 4x5.65 tray, lowering the chance of ghosting or internal reflection. However, placing a single filter into a traditional tray is not recommended as it is loose and can rattle. Matt Boxes with clamp-style filter holder mechanisms, such as the bright tangerine misfit atom, do not require any special trays or adapters, reducing the weight by half when compared to a 4 millimeter equivalent. You can also stack a 2 millimeter Super Slim filter with a standard 4 millimeter cinema filter to combine two filter effects while saving weight. The Super Slim filters are also compatible with our FireCrest MK2 holder, giving you even more options for using these filters. These Super Slim filters are available in 0.6, 0.9, 1.2, 1.8, and 2.1 densities. The new 2 millimeter tray is available as a standalone product or in a kit comprising of three or five filters. These Super Slim filters bring the finest of FireCrest technology at half the weight and cost of traditional cinema filters.
