Hoya 37mm HMC NDX4 Filter

A Hoya 37mm HMC NDX4 Filter is designed for those situations when excess light can be a problem, this can be a fundamental problem that we find on bright days or in the presence of snow. This neutral density filter provides a neutral grey colour to provide you with a uniformed spectrum providing improved colour balance.

Similarly, this filter is a great tool to provide long exposures and enables the photographer to use wider apertures.Easily screw this filter in to the front of the lens and it provides additional protection against dust, scratches or frontal blows that could cause great harm to the lens.

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).
