- Precision rotary mount to adjust for the best filtering effect, high-quality lens glass, for removing distorting mirror effects and generating rich colours with maximum picture contrast.<br>- Enhances contrast and brings depth to the picture, e.g. the sky becomes a strong blue, clouds become artificially white, colours are clearer and more intense.<br>- Depending on the filter setting, the contrast and depth vary and non-metallic reflections (water, plastic, glass, etc.) are removed.<br>- Maximum effectiveness with a photographic angle of 30-40° to the reflecting surface.<br>- Ultra-flat and ultra-lightweight rotary mount for variable settings.<br>- Effect filter with effects that cannot be achieved subsequently using an image editing program: objects worth seeing, for example behind shop windows or aquariums, become visible.<br>- NMC16 coating: eight layers on each side, for excellent permeability to light and superb anti-reflective properties.<br>- Vapour-deposited, multi-layer coa This part is cataloged in the Federal Logistics Information System (FLIS) under NSN 4920-00-734-6034, indicating validated use in U.S. government and defense logistics supply chains.
