Overview

The Tiffen 405CP 40.5mm Circular Polarizing Filter is a purpose-built optical accessory designed to tame reflections and deepen color saturation in both photography and videography. By selectively filtering polarized light, it cuts through glare bouncing off water, glass, and other non-metallic surfaces, revealing richer blues in skies and more vivid greens in foliage. Tiffen's proprietary ColorCore technology embeds the polarizing material between two layers of optical-quality glass, ensuring uniform color consistency and long-term durability that surface-coated alternatives often cannot match.

The ultra-slim ring profile is a key design choice for the 40.5mm size, which is commonly found on compact mirrorless lenses where vignetting risk is higher. The non-slip outer ring allows smooth rotation to fine-tune the polarization angle without struggling to grip the filter, and its water-resistant surface coating means you can confidently shoot near waterfalls, coastlines, or in light rain without worrying about damage. At just 40.5mm, this is a small and lightweight addition to your kit that delivers a meaningful visual improvement straight out of camera, reducing the need for post-processing glare correction.

Key Features

BRING OUTDOOR SCENES TO LIFE : Achieve richer color and contrast using the Tiffen 40.5mm Circular Polarizer Filter, a must-have camera lens accessory that helps deepen blue skies, enhance cloud detail, and improve overall color saturation for landscape, travel, and nature photography.

BUILT FOR SHARP, DEPENDABLE IMAGE QUALITY: Made with premium Schott B270 optical glass, Tiffen's Circular Polarizer maintains clarity while reducing unwanted glare, making this CPL filter a valuable addition to any Mirrorless, DSLR, SLR camera kits or even try out the CPL for I phones with Tiffen's iPhone Filter mount.

HOW A CIRCULAR POLARIZER WORKS : Rotate the circular polarizing filter while looking through your camera or viewfinder to control reflections and glare on water, glass, and other non-metallic surfaces. As you turn the filter, its polarization angle changes, allowing you to increase or decrease the amount of reflected light that reaches the camera sensor for precise control over glare reduction and image contrast. You'll also deepen blue skies, enhance color saturation, and improve overall image clarity, making it an essential tool for landscape, travel, automotive, and outdoor photography.

CAPTURE CLEANER, MORE PROFESSIONAL-LOOKING PHOTOS : Bring the CPL on every adventure whether you're photographing lakes, city skylines, mountain vistas, vehicles, or storefront windows; the circular polarizing effect helps reveal natural colors and details that can be hidden by reflected light.

READY FOR PHOTOGRAPHERS ON THE MOVE : Engineered with a Slim durable screw-in filter design, professional Tiffen packaging, and a padded black nylon pouch for storage and transport; compatible with lenses featuring a 40.5mm filter thread for convenient everyday carry and protection between shoots. Dimensions were not available on Tiffen.com and therefore are not included

Confident Compatibility: Find your lens size by locating the “Ø” symbol on the front rim, followed by the millimeter measurement, such as Ø58mm, and choose the matching filter for a secure, professional fit.

Frequently Asked Questions

No, the 405CP uses an ultra-slim ring design specifically engineered to prevent vignetting on both wide-angle and telephoto lenses.
No, the ultra-slim ring design is specifically engineered to prevent vignetting on both wide-angle and telephoto lenses at the 40.5mm filter size.
No. The ultra-slim ring design is specifically engineered to prevent vignetting on both wide-angle and telephoto lenses.
No. Tiffen designed this with an ultra-slim ring profile specifically to prevent vignetting on both wide-angle and telephoto lenses.
Simply rotate the outer ring of the filter while looking through your viewfinder or at your live view screen. The polarization effect changes as you turn it, letting you dial in the exact amount of glare reduction you want.
A circular polarizer is compatible with autofocus and metering systems in modern cameras, while a linear polarizer can interfere with those systems. For any camera with through-the-lens metering, a circular polarizer like this one is the correct choice.
A circular polarizer like this Tiffen filter is designed to work with autofocus and metering systems in modern cameras. A linear polarizer can interfere with these systems, making circular polarizers the standard choice for current digital cameras.
ColorCore is Tiffen's proprietary process where the polarizing material is laminated between two pieces of optical glass, providing consistent color and effect quality that resists degradation over time.
Yes, the circular polarizer works equally well for video and photography, reducing reflections and enhancing color saturation in both applications.
Yes, the filter is water resistant, providing protection during outdoor shoots in damp or variable weather conditions. The surface is also easy to clean and maintain.
Circular polarizing filters typically reduce light by about 1 to 2 stops, so you may need to compensate with a slightly slower shutter speed or wider aperture.
Yes. As a circular polarizer (as opposed to a linear polarizer), the 405CP is designed to work properly with autofocus and metering systems in modern cameras.
Absolutely. The circular polarizer works equally well for video, reducing reflections and enhancing color and contrast in footage.
Yes. Tiffen has given this filter a water-resistant coating, which provides extra protection during outdoor shoots in varied weather conditions.
ColorCore is Tiffen's proprietary process where the polarizing material is laminated between two pieces of optical glass, ensuring consistent color accuracy and long-lasting performance compared to surface-applied coatings.
Yes, the filter surface is water-resistant, offering protection during outdoor shoots in varying weather conditions and is easy to clean and maintain.
This filter fits lenses with a 40.5mm front filter thread. Check your lens cap or lens specifications to confirm your thread size before purchasing.
While it does provide a layer of physical protection for the front lens element, a circular polarizer reduces light transmission by approximately 1 to 2 stops, so it is best used intentionally rather than as a permanent lens protector.
ColorCore is Tiffen's proprietary process where the filter effect is sealed between two layers of optical glass, ensuring consistent color accuracy and long-term durability compared to surface-coated filters.
The water-resistant coating makes maintenance straightforward. Use a microfiber cloth or lens cleaning tissue with a small amount of lens cleaning solution to wipe the surface gently.
