These filters offer both amateur and professional photographers HOYA's famous quality at reasonable prices. They have multiple coatings applied to both surfaces to suppress reflection and increase light transmission.
The Hoya Multi-Coated Neutral Density (ND) Filter is an essential accessory for any photographer's camera bag. ND filters reduce the amount of visible light that enters the lens, allowing the user to utilise wider apertures or slower shutter speeds, particularly in bright conditions. ND filters work especially well for portraits by allowing the photographer to reduce the depth of field, producing pleasant background blur while keeping the subject in sharp focus. These filters are also often used to emphasize movement by permitting slow shutter speeds in bright light, giving life to photos that would otherwise look frozen in time.
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.
HOYA Pro1 Digital filters are recommended for enhancing the performance of todays multicoated lenses. The Black Almite Frame (BAF) is a black matte finish aluminum frame that reduces reflections to enhance contrast. In addition, the Black Rimmed Glass (BRG) reduces light reflection around the filter edge. Low Profile Frame (LPF) is an Ultra thin frame which helps avoid vignetting on wide-angle lenses, and the Knurled Edge Frame (KEF) aids easy attachment and removal.
