Hoya 49mm Color Spot Lens Filter (Yellow)

The Hoya 49mm Color Spot Yellow Lens Filter is a colored glass filter with a hole in its center. This special effect filter makes the central image stand out clearly while the background appears the color of the filter. The filter effect varies with the f-stop chosen and the focal length. The wider the aperture the softer the effect. The size of the clear circular area increases relatively with the selection of longer focal lengths.
