Scope: you can shoot a very blue sky, to eliminate or weaken the water reflection, shooting objects in the water, through the glass after the shooting of things.Filter Features:1. High-quality filter is destined to use pure optical glass material, optical stability, high uniformity.2. Multilayer coating, can filter ultraviolet and stray light, a large number of reflection caused by the glare glare phenomenon, showing a more realistic image effects.3. Ultra-thin ultra-light, high-definition high permeability, ultra-low reflectivity, reducing the refraction of the adverse effects of refraction.4. Open mold injection frame, the size of precision, ultra-dark no dark corners.5. Does not affect the PTZ self-test.6. Can be used with the lens hood at the same time, shooting better.7.
