Rear Magnetic Filter Holder: ARRI’s Unique Creative Innovation

One of the most ingenious and distinctive innovations of the ARRI Signature Prime series is its rear magnetic filter holder system. Each lens includes a mount that magnetically couples to the rear of the optic, allowing quick, tool-free insertion of 40.5mm rear glass filters or diffusion nets. This system offers several crucial advantages over traditional front-mounted matte box filters:

• No reflections or contamination: Positioned behind all optical elements, rear filters cannot generate internal reflections or unwanted flares.
• Compact and economical: 40.5mm filters are much smaller, lighter, and more affordable than 4x5.65" or large front circular filters.
• Instant changes: Magnetic coupling allows filter swaps in seconds without unmounting the lens from the camera.
• Rear element protection: The filter holder also protects the delicate rear optical element. ARRI advises the lens should never operate without this element installed.

Creative Uses of the Magnetic Filter Holder

• Diopter filters for macro: Dramatically reduce MOD for extreme close-ups without a dedicated macro lens.
• Graduated filters (ND, color): Exposure balancing or subtle color effects while keeping the front of the lens clean.
• Diffusion nets: Create vintage textures, Orton-like soft glow, 70s/80s looks with precise control.
• Special effects: Rear polarizers, custom diffusion, controlled vignetting and other creative experiments.

Important safety note: The rear magnetic filter holder must always remain installed on the lens, even if no filter is in use. Removing it exposes the rear optical element to dust and damage, and may affect the internal sealing of the lens.
