With a polarizing filter, you simply turn out the unwanted reflection - without any post-processing. pPrecise rotating mount for optimal adjustment of the filter effect, high-quality lens glass, to remove disturbing reflections and produce rich colours with good image contrast. Enhances contrast and brings depth to the picture, e.g. the sky becomes a strong blue, clouds become vivid white, colours clearer and more intense. Depending on the position of the filter, contrast, depth and non-metallic reflections (water, plastic, glass, etc.) are eliminated. Highest effect at a shooting angle of 30-40° to the reflecting surface. Ultra-flat and ultra-lightweight swivel mount for variable adjustment. Effect filter whose effect cannot be achieved afterwards with an image processing program: Sights worth seeing e.g. behind shop windows or aquariums become visible. NMC16 coating: eight layers on each side, for very high light transmission and very good anti-reflection coating Nano-coating for lotus effect: easy to clean, reduces fogging as well as renewed dirt adhesion, water, oil and dirt repellent. The front and rear sides of the filter are coated, so there is no loss of contrast or brilliance, ghost and double images are prevented. Ultra-thin wide frame: prevents vignetting. Hardly extends the lens stem. Filter holder made of black anodised metal and blackened inner edges prevent reflections. Edge sealing protects against soiling. Dimensional stability of the frame despite temperature fluctuations.
