Tiffen Black Fog 1/8 Rear Mount Filter for Arri Signature

Cinematic Diffusion for ARRI Signature Optics

The Tiffen Black Fog 1/8 Rear Mount Filter is a precision-engineered optical solution developed in collaboration with ARRI. Designed specifically for the ARRI Signature Prime and Zoom lens series, this filter integrates seamlessly into the lens's native magnetic rear filter holder. By placing the diffusion at the rear of the optical path, cinematographers can achieve a distinct, high-end look while maintaining the integrity of the lens's performance.

Instant Magnetic Installation

Forget complex tools or threaded adapters. This filter utilizes an integral ring of 12 high-power magnets that align perfectly with the ARRI Signature lens mount. This tool-free system allows for rapid changes on set, enabling DPs to swap filter types or strengths in seconds. The rear-mount design also significantly reduces the weight and bulk of the camera rig by minimizing the reliance on heavy front-mounted matte boxes.

Uniform Strength Across Focal Lengths

One of the primary advantages of the Tiffen rear-mount system is the consistency of the diffusion effect. Unlike front-mounted filters, where wider focal lengths often require heavier grades, a rear-mounted filter maintains the same filter strength regardless of how wide or tight the lens is set. A 1/8 grade provides a subtle, atmospheric softening that remains stable throughout your entire lens set.

Professional Black Fog Characteristics

The Black Fog series is part of Tiffen's Academy Award-winning lineup. The 1/8 grade offers a delicate touch of diffusion, softening highlights and smoothing skin tones without sacrificing essential detail. Manufactured using Tiffen's proprietary ColorCore Technology, each filter is built to withstand the rigors of professional production while delivering consistent results.
