SLR Magic 82mm Self-Locking Variable Neutral Density 0.4 to 1.8 and 86mm Solid Neutral Density 1.2 Image Enhancer Filter Kit

This SLR Magic Filter Kit contains a solid variable neutral density filter that can be mounted onto lenses with 82mm front threads and provides an exposure reduction of 1.3 to 6 stops. Additionally, an ultraviolet and infrared control filter is included, which can be mounted on top of the solid variable neutral density filter. The UV and IR control filter compliments the use of the solid variable neutral density filter by helping to maintain a proportion of infrared to visible light within a scene or image that does not result in unwanted color shifts, which can otherwise occur when using multi-stop, neutral-density filtration.

• SLR Magic 82mm Self-Locking Variable Neutral Density 0.4 to 1.8 Filter (1.3 to 6 Stops)

  The SLR Magic 82mm Self-Locking Variable Neutral Density 0.4 to 1.8 Filter is a solid variable neutral density filter that is designed to mount onto lenses with 82mm front filter threads and provides an exposure reduction of 1.3 to 6 stops. The 0.4 to 1.8 density creates a darkening of the entire image, allowing you to photograph with a wider aperture or slower shutter speed than normally required. The degree of density is easily controlled by rotating the front filter ring, helping you to predetermine the additional exposure length required. By slowing your exposure time or increasing your aperture, you are able to control depth of field and convey movement more easily. For easier, repeatable control over density settings, the front ring is visually demarcated with numbers representing different density values and includes a rotation lever to further enable fast and precise positioning of the front ring. Once the front ring is rotated into a position that corresponds to the desired amount of density, the filter's rear ring can then be turned to lock the front ring into place, helping to ensure consistent exposures.
  
  This filter is constructed from optical glass for clarity and color fidelity. It is multi-coated to prevent internal ghosting as well as reflections and also features an 86mm mount which helps to reduce the likelihood of vignetting when used with wide-angle lenses.

  Variable neutral density filter allows you to dial in differing amounts of density scene to scene.

  0.4 to 1.8 neutral density filter darkens the image, allowing you to photograph with a longer shutter speed or wider aperture than normally required.

  Providing a reduction of 1.3 to 6 stops, this filter allows you to control depth of field and convey movement more easily.

  Offers increased flexibility to use specific ISO settings or ISO films under bright ambient light.

  Provides increased exposure flexibility while using cinema or video cameras within a designated film frame rate.

  Multi-coated, optical glass for clarity and color fidelity as well as the prevention of internal ghosting and reflections.

  Side lever allows the filter glass to be easily rotated.

  Integrated exposure locking ring prevents accidental rotation of filter glass and changes to corresponding density values.

  86mm front mount helps to reduce the likelihood of vignetting with wide-angle lenses.

  Plastic filter case for storage and transport.

• SLR Magic 86mm Solid Neutral Density 1.2 Image Enhancer Filter (4-Stop)

  The SLR Magic 86mm Solid Neutral Density 1.2 Image Enhancer Filter is an ultraviolet and infrared control filter with a 16x filter factor that provides a 4-stop exposure reduction. It is useful for digital cinematography as well as still photography. While recording video with a CCD or CMOS camera, multi-stop neutral-density filters are frequently used to maintain proper exposure by compensating for increased light levels when widening the camera lens's iris to obtain a narrower depth of field. As the increased amount of light passes through multi-stop, neutral-density filtration, visible light is progressively blocked, while infrared light is allowed to pass through. As the proportion of infrared light that reaches the digital camera sensor becomes greater, the results can show unwanted color shifts, particularly in dark areas of the frame such as shadows, where the appearance of black is dominant.
  
  When the SLR Magic 86mm Solid Neutral Density 1.2 Image Enhancer Filter is applied, ultraviolet light waves along with infrared light waves are suppressed, helping to ensure that light falling on a digital camera sensor is limited to the visible spectrum. Its own 1.2 density creates a darkening of the entire image, allowing you to photograph with a wider aperture or slower shutter speed than normally required. By slowing your exposure time or increasing your aperture with this filter, you can control depth of field and convey movement more easily within a range of 4 stops without the need for additional neutral-density filters.

  This filter's optical design also allows it to be used on top of a separately available SLR Magic Self-Locking Variable Neutral Density 0.4 to 1.8 Filter that features 86mm front filter threads. Together, that filter combination can provide a 5.3 to 10-stop exposure reduction without visible cross patterns when rotating the variable neutral density filter's front ring to adjust the amount of density applied by the filter combination. When used alone or along with an SLR Magic multi-stop, neutral-density filter while recording with a digital sensor, potential infrared color shifts are prevented or minimized, preserving color accuracy throughout the frame. This filter may also be used to help ensure that the appearance of unwanted blue casts is reduced while recording digital video or still photos under daylight that also features intense ultraviolet light.
  
  The front and rear surfaces of an SLR Magic 86mm Solid Neutral Density 1.2 Image Enhancer Filter include interference coatings that allow the filter to limit the light that falls on a digital camera sensor to the visible spectrum. A nano coating offers protection to the filter substrate, and results in an improved beading effect when in contact with water for greater cleaning efficiency.
  
  This filter is constructed from optical glass for clarity and features an aluminum-alloy filter ring for durability while remaining lightweight.
