What sets our 39mm Circular Polarizing Lens Filter Plus+ apart is its ability to dramatically enhance your photography by increasing contrast and boosting color saturation. This high-quality filter is designed to cut out 99.9% of reflected light from water, glass, and non-metallic surfaces, allowing for bolder, more vibrant colors in your images. Constructed with the world's best glass, this filter features German Schott B270 optical glass, renowned for its superior quality and performance. This durable filter is coated with 20 layers of nano-coating, providing enhanced protection against water, oil, and scratches, while also ensuring easier cleaning. The multi-coated coating not only reduces reflections and glare but also facilitates higher maximum light transmission and a more consistent transmission curve. The result is sharper images, finer colors, and greater depth, making this filter an effective tool for any photographer.
