Tiffen launches diffusion filters for magnetic rear holder on ARRI Signature lenses

For the first time, filmmakers who are lucky enough to use ARRI Signature lenses can add Tiffen filters to the Magnetic Rear Filter Holder on each lens.

The ARRI Signature lenses' detachable Magnetic Rear Filter Holder has been a popular innovation from ARRI, and the new Tiffen diffusion filters for it - first shown at Cinegear - offer admirable no tools / no worries installation. Tiffen's integral ring of 12 high power magnets on each filter ring just line up with those on each Signature lens, opening the door to instant changeability, more creative options when it comes to strengths and varieties, and way less weight than with heavy matteboxes and filterholders placed in front of the lens.

There's a usefully large range at launch too. Users can choose from many different 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.

It's worth noting that there is a change to the way strengths are affected when using the rear mount system too. 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."

Pricing starts at $389 per filter.
