Rodenstock 67mm Center Filter

Rodenstock 67mm Center Filter - When working with ultra-wide-angle lenses, the fall-off of illumination towards the corners is sometimes disturbing. For this reason, concentrically graduated Center Filters have been designed to compensate for this vignetting. This filter features a 1.5 stop value (5x exposure increase).

These filters have a transparency which increases gradually from the center to the edges of the filter where it reaches full transparency. The transmission is independent from the wave length of the visible spectrum.
