Hoya 55.0 Variable Density II ND3-400 Filter

The HOYA Variable Density II is a filter with adjustable density that covers an ND range of 1.5 to 9 stops (ND3-400). The filter features a newly designed rotating frame that includes a convenient knob for improved handling. For still images, a variable density filter allows photographers to shorten the shutter speed according to their intentions when this is not possible due to camera limitations. In video recording, it is important that the shutter speed matches the set frame rate, ideally double the frame rate. By using a variable density filter, the shutter speed can be adjusted accordingly to achieve the natural and smooth motion desired in video recordings, as illustrated in the following image.
