Kenko PL Filter Zeta Quint Circular PL for increasing contrast and removing reflections 211427 40.5mm

A circular polarizing filter that clearly reproduces the original colors of the subject by suppressing the reflection of unnecessary light. You can obtain a ``color contrast effect'' that suppresses reflections on water and glass surfaces, and deepens the color of the blue sky. [Approximately 1EV brighter amount of transmitted light] By using a high transmittance polarizing film, the amount of transmitted light is approximately 1EV brighter than a regular C-PL filter. The viewfinder remains bright and easy to see, providing a PL effect. It is less affected by shutter speed reduction and can be used even in low light conditions. Exposure multiplier: 1.7 to 2.2 times (approx. 2/3 to 1 stop). [Reliable tempered glass] Optical glass is heat-treated and chemically strengthened, making it approximately 3 times stronger than regular glass and protecting your precious lenses. Even if it breaks, the pieces will break into fine particles, preventing major injuries and accidents. [The first duralumin frame in a filter] This is the first filter to use a duralumin frame, which is harder than an aluminum frame. It resists distortion even when subjected to impact, protects the glass from pressure caused by external factors, and maintains the flatness of the glass. [Dust-free coat that is resistant to stains] It is resistant to water droplets and fingerprints, and even if it does get dirty, it can be easily wiped off. This coat makes cleaning during and after shooting easier. [ZR coating that achieves ultra-low reflection] By reducing the reflectance on the glass surface to less than 0.6% on one side in the visible light range, the effect of attaching a filter on image quality is brought to a close to zero. We support a wide range of lenses, from the latest high-performance, high-resolution lenses to old lenses that you want to enjoy.
