Hoya Softon-A Filters create a picture with a clear focus and a soft gradation. A filter randomly arranging minute lenses shaped like drops of water on the surface of an acrylic board scatters the light and results in a soft focus.
Note:
Clear focus and soft gradation effect is especially evident on an object with a point light source. Pro 1 Digital filters are ultra thin, but have a front thread

aluminum, satin finish almite frame, which reduces reflections

Low Profile Frame

Knurling Edge Frame
These filters are equipped with a straight knurling edge for non-slip, easy attachment and removal
UV Protected Case
Filter cases are UV protected, which further lengthens the life of filters
