Kenko Effect Filter Starry Night Prosofton φ72mm, Light pollution reduction & soft effect, for shooting starscape, Made in Japan 549629

The Kenko Starry Night Prosofton is a effect filter that combines the effects of ‘Starry Night,’ which cuts light pollution, and ‘Prosofton,’ which beautifully blurs the point light sources of stars, in one filter, making it the perfect effect filter for shooting starscape. Since two effects can be achieved with a single filter, it eliminates the need for stacking filters and reduces the risk of vignetting and flare. The thin frame is designed to avoid vignetting even when shooting with wide-angle lenses. Main Features [Effect1] Light pollution-cutting effect to restrain color casts caused by city lights Sodium-vapor and mercury lamps and other streetlights cause yellow and orange color casts in the night sky, but "Starry Night Prosofton" cuts out only the light of specific frequencies that correspond to these colors, allowing for natural color reproduction. [Effect2] Soft effect to make the constellation picture stand out while the landscape and background remain clear A soft effect that makes picture of bright stars blur beautifully and brings constellations to life. "Starry Night Prosofton" is equivalent to "Kenko PRO1D Prosofton Clear(W)". The softening effect is applied only to point light sources such as stars, and does not affect the surrounding scenery, making it suitable for starry landscapes or when you do not want to apply softening effects to anything other than stars. [Other Features] ■Multi-coating to suppress flare and ghosting when filter attach. ■The black rimmed glass to minimize reflections inside the frame. ■Thin frame design prevents vignetting even when using ultra-wide angle lenses. ■Knurled frame for easy attachment and removal. ■Lens cap can be attached. Please note that: ・The exposure magnification factor is 1/3 stops, so when shooting the starry sky with manual exposure, if you shoot with the same settings as with no filter, the image will be underexposed. ・The effect can be achieved in AWB (Auto White Balance) mode, but you can set to fluorescent light mode or adjust the color temperature according to your preferences. ・The filter will not completely cut the light from sodium-vapor lamps and mercury lamps. Additionally, as light pollution is produced from numerous light sources, this filter cannot cut all light pollution.
