SmallRig 67mm Magnetic Circular Polarizer CPL Filter - Fast On/Off

In this review of the SmallRig 67mm Magnetic Circular Polarizer CPL Filter the bottom line is simple: it is a practical, quick-to-use polarizer for photographers and mobile shooters who need reliable glare control and richer skies without complex mounting. The magnetic system paired with the included 67mm threaded filter ring makes switching filters fast, and the 28-layer multi nano coated AGC glass keeps images clean while resisting water, oil, and scratches. For anyone who values speed and durability in the field, this CPL is worth considering.

Key Features

• CPL Filter Function: Removes reflections from non-metallic surfaces to increase saturation and improve contrast for bluer skies and clearer water.
• Magnetic Design: The magnetic attachment lets photographers install or remove the filter quickly and reliably without screwing on and off repeatedly.
• Camera Compatibility: The included 67mm threaded filter ring enables direct mounting on lenses with a 67mm thread for a convenient lens workflow.
• Phone Cage Compatibility: Works with SmallRig mobile phone cages when matched to the proper 67mm M mount or T mount ring sold separately for phone rigs.
• Multi-coating AGC HD Glass: 28 layers of nano coating on both sides improve light transmission while protecting against water, dirt, oil, and scratches.
• Durable Build: CNC aluminum alloy frame reduces the chance of vignetting on wide-angle lenses while providing a robust housing for the glass.

Who It's For

Photographers who shoot landscapes, travel scenes, and outdoor portraits will benefit most from this circular polarizer because it cuts surface reflections and deepens color without elaborate setup. Mobile content creators using SmallRig phone cages can also integrate the filter into their rigs for improved sky and water rendering when paired with the appropriate mount ring.

Those with lenses that do not use a 67mm thread or users who prefer screw-on-only systems without magnetic parts should look elsewhere; also, if you require a full filter kit with multiple diameters included, this single-size solution may not meet that need.

Pros & Cons

Pros

Frequently Asked Questions

Can I use this on other lens sizes?
Yes, but only with step-up or step-down adapter rings; the filter itself is 67mm and the package includes a 67mm threaded ring.

Is the magnetic attachment secure for outdoor use?
The enhanced magnetic attraction is designed to be safe and reliable for normal shooting, but users should still handle the filter carefully in extreme conditions.

Will the coating affect colors?
The AGC glass and 28-layer nano coating are designed to preserve true color and maintain light transmittance without color cast.
