CPL Filter 72mm — Circular Polarizing Filter for Canon, Nikon, Sony, Pentax DSLR Cameras Key benefits - Reduce reflections and glare from water, glass, wet leaves and non-metallic surfaces to reveal more scene detail. - Increase color saturation and contrast for deeper skies and richer foliage without post-processing. - Give photographers control over atmospheric reflections and scattered light to produce cleaner, more defined images. What it is - Type: Circular Polarizing Filter (CPL) — designed for photography applications. - Function: A polarizer lets light with a specific polarization pass and blocks other polarizations, helping you manage reflections and enhance color and contrast in-camera. Specifications - Size: 72mm screw-in filter thread — fits lenses with a 72mm filter mount. - Filter material: optical glass for image-quality clarity. - Thread material: aviation aluminum for precise threading and lightweight durability. - Compatibility: Suitable for Canon, Nikon, Sony, Pentax DSLR cameras (use with lenses that accept 72mm filters). Performance and usage notes - Optical glass preserves image clarity while the polarizing effect reduces unwanted glare and increases scene contrast. - The aviation aluminum thread provides a secure, long-lasting mount and smooth attachment to compatible lenses. - Adjust the strength of the effect in-camera to balance reflection reduction and color saturation for the scene and lighting conditions. Practical scenarios - Landscape photography: Darken blue skies, increase cloud contrast, and reduce surface glare from rivers or wet rocks. - Outdoor product or architectural shots: Minimize reflections on windows, display cases, or polished surfaces to capture more detail. - Travel and nature photography: Improve color saturation and reduce atmospheric haze when shooting foliage, bodies of water, or bright skies. What to check before purchase - Verify your lens has a 72mm filter thread (usually stamped on the front or side of the lens barrel). - Confirm your camera system (Canon, Nikon, Sony, Pentax) and lens combination will accept a 72mm screw-on CPL. A reliable accessory for photographers who need better control of reflections, improved in-camera color and contrast, and durable construction using optical glass and aviation aluminum.
