IRIS Mobile filter system

The PolarPro Iris Mobile Filter System is a premium optical solution designed for mobile filmmakers and content creators who want to match their smartphone footage with professional mirrorless or cinema cameras. By default, smartphone cameras compensate for bright lighting by forcing an extremely fast shutter speed, which results in choppy, unnatural video.

The Iris system solves this by introducing high-grade physical Neutral Density (ND) filters. These act like sunglasses for your phone's lens, allowing you to lower the shutter speed to cinematic levels (following the 180-degree shutter rule) to introduce smooth, natural motion blur.

Features

Cinematic Shutter Control

Allows you to drop your smartphone's shutter speed down to double your frame rate (such as locking at 1/50th of a second for a 24fps video), matching the motion characteristics of traditional cinema cameras.

CinemaSeries Optical Glass

Constructed using PolarPro's top-tier glass elements featuring a low refractive index and multi-coatings to prevent ghosting, flares, and color shifting.

Universal Machined-Aluminum Mount

Features an expandable, high-durability aluminum frame that clips quickly over the smartphone's camera lens module, fitting safely whether you use a phone case or run a bare device.

Dynamic Light Management

Includes three distinct fixed filters to smoothly adapt to shifting outdoor environments, preventing overexposure without relying on software degradation.

Pocket-Sized Portability

The entire system, including the mounting bracket and glass pieces, collapses down into a slim hardshell storage case designed to slip easily into small gear pockets.
