Review Summary
From a clear center, the Cokin Radial Zoom fiter duffuses colors and light in the form of rays towards the picture edges, like a fireworks display.
By night, it's the filter to use for neon signs, illuminated monuments, general views of the lights of the city, and the brilliantly lit avenues. By day, highly-colored subjects & backgrounds irradiate their colors with the same intensity.
Recommended for focal lengths of 35-50mm and apertures of f5.6/f8.
