The 72mm C-Series Variable ND2 to ND400 Filter from K&F Concept reduces light intake from 1 to 8.66 f-stops. Intended for long exposure and motion blur, it is suitable for rivers and waterfalls, especially under strong light. The filter is made of high-end Japanese optical glass. The ultraslim filter frame is designed of aluminum alloy, which is only 7.3mm thick. Its design prevents wide-angle vignetting and is not recommended for use with wide-angle lenses with focal lengths of 35mm.
