Now filmmakers who use Signature lenses can add their favorite Tiffen filters to the ARRI Magnetic Rear Filter Holder on each lens. Thanks to Tiffen's precise integration with this brilliant system, there is no change to the native lens required to use the new Tiffen Filters. Installation could not be easier and there's no special tech required. There are no tools and no worries. Tiffen's ring of 12 high power magnets on each filter ring perfectly match up with those on each Signature lens. The result is instant changeability and more creative options when it comes to strengths and varieties. It also means less weight than with heavy matteboxes and filterholders in front of the lens.
Voila! The simple-to-use magnetic rear-mount system opens the wide world of Tiffen filters. Cine professionals can choose from the large range of diffusion filter types—including Black Fog, Night Fog, Black Pro-Mist®, Antique Black Pearlescent, Antique Pearlescent, Antique Satin, Smoque®, the array of Glimmerglass® and many more. As with front-of-the-lens filters, Tiffen rear filters come in a choice of grades from 1/8 to 2. But, there is an interesting change to the way strengths are affected when using the new system. As Jon Fauer ASC explains, "When mounted on the rear, you can use one filter strength, for example ¼, on your entire range of focal lengths. You do not have to change strengths depending on how wide or tight you are. This is different from when you add a filter to the front of the lens—where you probably use a heavier grade for wide angles (maybe ½ or 1) and a lighter grade for tighter angles (maybe ⅛ or ¼). Now, you only need one filter strength at the rear of each lens in a set."
Like the rest of Tiffen’s Emmy® & Academy Award®-winning filters, this new filter category is crafted in the USA with optical grade glass. To promote long life and image clarity, only Tiffen filters are manufactured using the exclusive Colorcore Technology® process that laminates the filter substrate between two parallel elements of optical glass, then grinds and polishes them to a precise tolerance of 1/10,000th of an inch flatness.
