The Hoya Pro 1 Digital ND16 Filter is a dark neutral density filter with a filter factor of 16, giving a 4-stop light reduction. This is a great filter for reducing shutter speeds to capture motion such as in water, foliage or people. For example, in bright daylight the slowest shutter speed possible without a filter could be 1/60 sec at f/22. By adding the Hoya Pro 1 ND16 neutral density filter, the 4 stop reduction in light means a shutter speed of 1/4 sec would be possible. Another use of the ND16 would be controlling depth of field. With a strong ND16, a much wider aperture can be used. Wide apertures like f 1.4 & f 1.8 create a very shallow depth of field & have the effect of isolating the subject from the background, but may not be useable under very bright conditions. Using the Hoya Pro 1 ND16 neutral density filter to reduce the light solves this problem. ...

The Hoya 77mm Pro 1 Digital ND32 Filter is a dark neutral density filter with a factor of 32, giving a 5-stop light reduction. This is a great filter for reducing shutter speeds to capture motion such as in water, foliage or people. For example, in bright daylight the slowest shutter speed possible without a filter could be 1/60 sec at f/22. By adding the Hoya Pro 1 ND32 neutral density filter, the 5 stop reduction in light means a shutter speed of 1/2 sec would be possible. Another use of the ND32 would be controlling depth of field. With a strong ND32, a much wider aperture can be used. Wide apertures like f 1.4 & f 1.8 create a very shallow depth of field & have the effect of isolating the subject from the background, but may not be useable under very bright conditions. Using the Hoya Pro 1 ND32 neutral density filter to reduce the light solves this problem. ...

The Hoya 77mm Pro-1 Digital ND4 Filter reduces the amount of light entering the lens by 2 f/stops, allowing wider apertures to be selected, which is perfect for portraiture to reduce depth of field. Subject appears crisp & clear while the background becomes a soft blur. Alternatively, the ND4 Filter can be used to allow longer shutter exposures than would otherwise be possible & is widely used for subjects such as waterfalls & other nature scenes to blur the moving elements & emphasize the movement. ...

The Hoya 77mm Pro 1 Digital ND64 Filter is a dark neutral density filter with a factor of 64, giving a 6-stop light reduction. This is a great filter for reducing shutter speeds to capture motion such as in water, foliage or people. For example, in bright daylight the slowest shutter speed possible without a filter could be 1/60 sec at f/22. By adding the Hoya Pro 1 ND64 neutral density filter, the 6 stop reduction in light means a shutter speed of 1 sec would be possible. Another use of the ND64 would be controlling depth of field. With a strong ND64, a much wider aperture can be used. Wide apertures like f 1.4 & f 1.8 create a very shallow depth of field & have the effect of isolating the subject from the background, but may not be useable under very bright conditions. Using the Hoya Pro 1 ND64 neutral density filter to reduce the light solves this problem. ...

The Hoya 77mm Pro-1 Digital ND8 Filter reduces the amount of light entering the lens by 3 f/stops, allowing wider apertures to be selected, which is perfect for portraiture to reduce depth of field. Subject appears crisp & clear while the background becomes a soft blur. Alternatively, the ND8 Filter can be used to allow longer shutter exposures than would otherwise be possible & is widely used for subjects such as waterfalls & other nature scenes to blur the moving elements & emphasize the movement. ...

Creates a picture with a clear focus & a soft gradation. This effect is especially evident on an object with a point light source. A filter randomly arranging minute lens shaped like drops of water on the surface of a acrylic board scatters the light & results in a soft focus. ...

The Hoya 77mm Pro-1 Digital Star-4 Filter adds a dramatic four-cross flare to very bright areas, giving a soft-focus effect. The Star-4 Filter is ideal for photographs of night scene illumination or other scenes with strong reflections & gives them an artistic twist. ...

The Hoya 77mm Pro-1 Digital UV is a multi-purpose fine-weather filter that absorbs the ultraviolet rays which often makes outdoor photographs hazy & indistinct. A multi-purpose filter for colour as well as black & white film & digital photography, the clear UV filter can also be left on the lens to serve as a permanent lens protector. ...

The Hoya 77mm REVO SMC Circular Polariser Filter means that you can significantly reduce reflections & glare from non-metallic surfaces. The REVO SMC polarising filter also enables colours to become more saturated & appear clearer with better contrast, this effect is often used by landscape photographers to increase the contrast & saturation in blue skies & white clouds. The REVO SMC Circular Polariser filter has been designed with a super-slim aluminium frame to reduce vignetting & is rotatable to allow full control over the desired effect. Hoya's SMC (Super Multi Coating) is applied to both front & rear glass surfaces to increase light transmission & prevent reflections. The coating is further protected with a clear water & stain resistant surface to allow easy care & handling of REVO filters in the field. The Hoya REVO SMC Circular Polarising filters are available in sizes from 37mm to 82mm diameter. ...

Made in Japan, the Hoya 77mm REVO SMC Protector is a professional quality filter with slim aluminium frame designed to protect the front element of your lens from dust & knocks. Manufactured using precision optical glass that is carefully smelted & blended to yield perfect optical results, the filter also features an enhanced Super Multi Coating formula to greatly reduce or eliminate reflections off the surface of the glass.
