Tiffen 43POL 43mm Standard Rotating Polarizer Filter

The Tiffen 43POL is a 43mm standard rotating polarizer filter designed to reduce reflections and glare from non-metallic surfaces such as water, glass, and foliage. By rotating the filter's outer ring, photographers can control the intensity of the polarizing effect, deepening blue skies, saturating natural colors, and cutting through haze to improve overall contrast and clarity. The effect is achieved optically at the time of capture, producing results that are difficult to replicate with software alone.

This is a linear polarizer rather than a circular polarizer, which is an important distinction. Linear polarizers perform the same optical function but can disrupt the phase-detection autofocus and through-the-lens metering systems found in most modern DSLRs and mirrorless cameras. This makes the Tiffen 43POL best suited for manual-focus cameras, older film SLRs, or any setup where autofocus and auto-metering are not required. The filter threads onto any lens with a 43mm front thread and adds very little weight or length, keeping compact lens setups streamlined.
