HOYA Filter 67mm 2X (0.3) Neutral Density Multi Coated Glass Filter

What this filter does

The Hoya 67mm 2X (0.3) Neutral Density Multi Coated Glass Filter reduces the amount of light entering the lens by one f-stop without shifting colour balance. It is intended for photographers who need wider apertures or slower shutter speeds in bright conditions. Multi-coated glass helps suppress flare and ghosting. The 67mm thread fits lenses with that specific filter diameter.

Who should use it and who should not

This filter suits photographers who want to maintain a narrow depth of field in strong daylight or create motion blur with longer exposures. It also helps users of high-speed film avoid overexposure when lighting is intense. It is not for buyers who need a greater reduction in light, such as two or more stops, or who require a different thread size for their lenses.

The specification that decides fit

The critical specification is the 67mm thread diameter; the filter will only mount on lenses with a matching 67mm front thread. The .3 density factor, which corresponds to a 2X filter factor, determines the exact amount of light reduction provided. Verify both values against your lens before purchasing.
