Tiffen has released a magnetic rear mount filter system for ARRI signature lenses. The system allows filmmakers using ARRI’s Signature Lens line of lenses to add any Tiffen filter to each lens’ ARRI magnetic rear filter holder.
The Signature lens uses a detachable magnetic rear filter holder. With this, users do not need to modify the native lens to use the filter. Easy to install, no special skills or tools required. Tiffen’s integrated ring features 12 high-power magnets in each filter ring that perfectly match the magnets in each signature lens. The result is instant interchangeability and more creative options. It’s also lighter than having a heavy matte box or filter holder in front of the lens.
This new system will expand the world of Tiffen filters. Filmmakers can choose from a wide variety of diffusion filters including Black Fog, Night Fog, Black Promist, Antique Black Pearlescent, Antique Pearlescent, Antique Satin, Smoke and Glimmerglass. Like the front filters, Tiffen rear filters are available in grades from 1/8 to 2.
Using the same system changes the impact on strength. ASC’s Jon Fauer commented:
Fauer: The rear mount allows one filter strength, say 1/4, to be used at all focal lengths. You don’t have to change strength for wide or tight. This is different than adding a filter in front of the lens. Use a heavier grade (perhaps 1/2 or 1) for wide angles and a lighter grade (perhaps 1/8 or 1/4) for narrower angles. This means that only one filter is required for the rear element of each lens.
Like all of Tiffen’s Emmy and Academy Award-winning filters, this filter category is manufactured in the USA from optical grade glass. To ensure longevity and image clarity, Tiffen’s filters are manufactured using a proprietary ColorCore Technology process that sandwiches the filter substrate between two parallel pieces of optical glass and polishes it to a flatness of 1/10,000 inch. ing.
