The Tiffen 4 x 5.65" Linear Polarizer Filter emerges as your ally in conquering reflections and glare by expertly sieving polarized light stemming from non-metallic surfaces. As sunlight collides with air molecules, it undergoes partial polarization due to electron interactions, resulting in scattered light that mimics a hazy effect. The polarizing filter takes charge, orchestrating and sieving this directionally polarized light at a right angle to the reflected light, engendering the absorption of a significant portion. This transformation bestows a striking reduction in reflections and glare from non-metallic surfaces, unveiling heightened sky and foliage saturation.

Distinguished by its absence of an additional quarter wave plane, a linear polarizer diverges from its circular counterpart. The circular polarizer integrates the quarter wave plane to circularly polarize linearly polarized light, aligning with auto focus and exposure functions. In contrast, the linear polarizer's breakdown and filtration of light lead to a departure in in-camera auto focus and exposure precision. Circular polarization reinstates the compatibility of these functions by facilitating circularly polarized light.

Embrace this filter's prowess when operating sans in-camera exposure metering or autofocus. Its non-coated composition generously offers an average light transmission of around 40%, bridging a harmonious connection between light and imagery.

Tiffen's indomitable legacy, upheld through the ColorCore technology, takes center stage in crafting this filter. The meticulous process encapsulates the filter substrate within dual layers of optical glass, fine-tuning the assembly to an astonishing precision of 1/10,000th of an inch. The result stands as a testament to excellence, spanning 4 x 5.65" / 101.6 x 143.5mm, and beckoning you to explore a world of refined visual storytelling.

• Helps to reduce reflections and glare by filtering out light that has become polarized due to reflection from a non-metallic surface.
• Polarizing filters arrange, and filter, directionally polarized light perpendicularly to the reflected light, allowing for the absorption of much of the light.
• Clears up haze in distant landscapes and provides more saturated, vivid colors.
• Strongest effect when used at a 90° angle from the sun.
• Recommended when not using in-camera exposure metering or autofocus.
• Non-coated.
• Approximately 40% average light transmission.
• 2.5x filter factor reduces exposure by 1.3 stops.
• Constructed using ColorCore technology.
• Filter Pouch for storage and transport.
