Overview

The Tiffen 25mm Circular Polarizer is a specialty-sized filter built for lenses with a 25mm front thread — a size commonly found on compact cameras, small-format video lenses, and certain specialty optics. Like all circular polarizers, it works by selectively blocking polarized light waves, which in practical terms means it reduces reflections and glare from surfaces like water, glass, and foliage while simultaneously deepening sky tones and boosting overall color saturation. The effect is adjusted by rotating the filter's outer ring while observing the scene, giving you real-time control over the intensity of polarization.

Tiffen is a well-established name in photographic filters, and this model maintains compatibility with autofocus and through-the-lens metering systems, which is the key advantage of circular polarizers over their linear counterparts. The primary consideration with this particular filter is its 25mm size — buyers should confirm their lens's filter thread before ordering, as 25mm is not a standard size for most interchangeable camera lenses. For those with compatible optics, it provides a genuine optical improvement that's difficult to fully replicate in post-processing, particularly the selective reduction of reflections and the natural enhancement of sky contrast.

Key Features

ULTRA-SLIM AND DURABLE FRAME: The Tiffen Circular Polarizer slim 25mm ring design ensures there’s no vignetting on wide-angle and telephoto lenses, keeping your image sharp and clean from edge to edge. The Tiffen Circular Polarizing non-slip ring allows for easy installation and removal, offering both durability and convenience for photographers and videographers.

Classic Circular Polarizer for Color & Contrast Control: Reduces glare and unwanted reflections from non‑metallic surfaces, enhancing color saturation and contrast for skies, water, foliage, and cinematic outdoor imagery.

Smooth Rotating Polarization Control: Allows precise adjustment of polarization intensity via a smooth rotating ring, giving filmmakers and photographers direct visual control as shooting conditions change. Tiffen Circular Polarizer filters are ideal for all types of photography and video projects. This filter provides a richer color and contrast on your projects.

IDEAL FOR PHOTOGRAPHY AND VIDEOGRAPHY: Tiffen Circular Polarizer filters are ideal for all types of photography and video projects. This filter provides a richer color and contrast on your projects.

Made from Optical Glass: Tiffen's optical glass provides unparalleled performance trusted by professional cinematographers and professional photographers for over 80 years.

Pros & Cons

👍 Pros

Effectively reduces glare and reflections from non-metallic surfaces like water and glass
Deepens blue skies and enhances overall color saturation without post-processing
Circular polarizer design maintains full compatibility with autofocus and metering systems
Compact and lightweight, adding minimal bulk to small 25mm-threaded lenses

👎 Cons

25mm thread size fits a very limited selection of lenses, reducing versatility across a lens kit
Reduces light transmission by approximately 1-2 stops, requiring exposure compensation in dim conditions
Rotating the filter to find the optimal polarization angle can be fiddly on very small lenses
No multi-coating mentioned, which may affect flare resistance compared to higher-end polarizers

Frequently Asked Questions

What lens thread size does this polarizer fit?

This filter is designed for lenses with a 25mm front thread diameter. This is a relatively uncommon and small size, so verify your lens's filter thread size before purchasing — it's typically printed on the front of the lens or listed in its specifications.

How do I adjust the polarization effect?

Simply rotate the outer ring of the filter while it's mounted on your lens. As you turn it, you'll see reflections and glare diminish or intensify through your viewfinder or LCD screen. Adjust until you achieve the desired effect for your scene.

Does this filter reduce the amount of light entering the lens?

Yes, circular polarizers typically reduce light transmission by about 1 to 2 stops. You may need to compensate with a slightly slower shutter speed, wider aperture, or higher ISO when shooting in lower light conditions.

Will this filter affect autofocus or metering accuracy?

No. Circular polarizers are specifically designed to be compatible with modern autofocus and metering systems, unlike linear polarizers which can interfere with these functions.
