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.
Digital multi-coated filters greatly reduce the appearance of lens flare and ghosting caused by reflections.
Black Almite Frame

Ultra thin filter frames to help avoid vignetting on super wide angle lenses are also designed to hold a lens cap.
Knurling Edge Frame
These filters are equipped with a straight knurling edge for non-slip, easy attachment and removal.
UV Protected Case
