ProOptic - 82mm Variable Neutral Density Filter, 2 to 8 Stops

The Tiffen Variable ND filter is a unique, versatile and flexible tool, affording you the convenience of using several Neutral Density filters all in one. Primarily used as a photographic tool for controlling depth of field and exposure, the Variable ND is being sought in the video market as well because it is fast, easy to use, small, lightweight, and does not require additional accessories such as a matte box. The Tiffen Variable ND filter operates on the same principle as a Circular Polarizer - rotate until you reach your desired effect and shoot. It allows you to have continuous control over the amount of light coming through your lens in an approximate range of 2 (ND 0.6) to 8 (ND 2.4) stops - while maintaining the integrity of your image.

This kit with 3 filters provides a variety of creative effects for your photography. The UV protector lens filter, 812 warming lens filter and circular lens polarizer fit conveniently in the included 4-pocket filter pouch for storage and easy transport.

The ProOptic 77mm Variable Neutral Density Filter benefits all types of imaging devices with lenses, whether analog film cameras or digital SLRs to continuously control the amount of light coming through the glass, in an approximate range of ND2 (ND 0.6) to ND8 (ND 2.4) stops, maintaining the integrity of the image. The ProOptic VND quickly counteracts lighting conditions that would otherwise force a photographer to abandon the use of high ISOs or preferred wider apertures in bright outdoor conditions. Run-and-gun videographers and location photographers revel in this small and lightweight solution over more cumbersome accessories like matte boxes with delicate ND filter gels. The ND, or neutral density filter, reduces the intensity of all visible light wavelength equally without influencing the color balance, fidelity, and sharpness. VND, or variable neutral density, grants the user power over the degree of ND effect by rotating the front glass element. The two layers of polarized material interact to limit rays by as much as eight stops of light, 0.39% of the full exposure, to ND 2.4. Selectively reducing the amount of light, lowers the exposure enough to record the illusion of movement in subjects such as streaking runners, rushing waters, billowing clouds, and special effects at night like car light trails, where they typically would be frozen in time. Another benefit is aperture control to allow a wider value, resulting in a narrow range of focus, helping separate subjects from their background. Wide-open apertures are known for gorgeous Bokeh and distinct soft blur aura. The ProOptic 77mm Variable Neutral Density (VND) Filter places the choice in your hands.
