A versatile paper type filter developed for photography of starry landscapes - Kenko REAR PROSOFTON set Bright stars are softened to highlight the constellations: With REAR PROSOFTON, bright stars are softened and the differences in brightness and colour of the stars are clarified, so that the constellations are highlighted. Stars are less likely to be elliptical: REAR PROSOFTON is a leaf filter used on the back of the lens, so it can be used with ultra-wide angle lenses where a screw filter cannot be attached in front of the lens. When a screw-in soft filter is used on a wide-angle lens, bright stars at the edge of the image are extended radially, but with the REAR PROSOFTON the radial extension is barely noticeable. Three types of soft focus effects can be used according to your preference: The set contains three types of soft filters with different softening effect strengths. You can choose the blur filter with the desired effect depending on the lens and situation.
