Hoya 46mm HMC NDX4 Filter

A Hoya 46mm HMC NDX4 Filter makes it possible for slower shutter speeds to be used, in particular with fast films, to record movements in subjects including waterfalls, clouds, cars and trucks, rivers etc.

Conveniently enable cine and video cameras (which have fixed shutter speeds) to capture subjects which include snow, on the beach or many other well lit scenes that might induce over-exposure.

This Hoya neutral density filter diminishes the depth of field by allowing for wider apertures to be implemented, this aids to divide a subject from their background. It will lower the effective ISO of high speed film and also allows for it to be applied outdoors in bright light scenarios.

Product features:

• Neutral density filters provide wider apertures or longer exposures devoid of impacting colour balance.
• Allows slow shutter speeds to be used, to record motion in subjects such as waterfalls, clouds, vehicles, oceans etc.
• Decreases depth of field by allowing wider apertures to be used, that will help separate subjects from their background.
• Neutral Density Factors are 4x = ND.6 (exposure adjustment = 2 stops, reduces ISO 1/4).
