Product details:

The ND32 is a dark neutral density filter with a filter factor of 32, meaning there is 5-stop light loss. This is a great filter for slowing down shutter speeds to capture motion. An example: In daylight, maybe the slowest shutter speed possible without a filter could be 1/60 sec at F/22 By adding the HOYA PRO1 ND 32, a shutter speed of 1/2 sec would be possible. Another use of the ND32 would be controlling depth of field. With these strong ND filters, a much wider aperture can be used. Wide apertures like F/1.4 and F1.8 create a very shallow depth of field and have the effect of isolating the subject from the background. Creative possibilities are endless with this type of filter. KEY FEATURES Digital Multi-Coated Digital multi-coated filters greatly reduce the appearance of lens flare and ghosting caused by reflections. Black Almite Frame Filters feature a black matte aluminum satin finish almite frame which reduces reflections. <
