This filter controls reflections and vividly expresses colors. It removes surface reflections from water, glass, etc., and deepens the color of the blue sky, resulting in very vivid colors for foliage, mountains, and buildings. A newly developed "wide-band 1/4λ phase difference plate" is used to prevent "color shift in the viewfinder image" caused by interference with the half mirror of a single-lens reflex camera. The thin frame design allows for safe use with wide-angle lenses. A rotating frame is employed. The filter part rotates, allowing you to check the effect in the viewfinder while shooting. This PL filter is perfect for those seeking high-quality performance at an affordable price. It can also be used with film cameras. - Model: PRO1D C-PL(W) 72mm Thank you for viewing.
