Hoya HMC NDx400 Filter 55mm

This is a Hoya multi-coated special effects filter suitable for film and digital.

Photographing solar eclipses and ultra-bright light sources can be extremely dangerous.

This 55mm HMC NDx400 filter reduces light values by 9 stops to less than 1/500th of its original intensity and allows safe photography. It can also be used to achieve super slow shutter speeds in daylight to render moving subjects invisible.
