Overview

Overview

The Tiffen 4 x 5.65 Mattebox Multi Rota Pola Tray - Variable Neutral Density is ideal for matteboxes without a rotating filter stage or for those instances where a secondary rotating filter stage is required in a non-rotating stage. The Tiffen Multi Rota Pola Tray is designed to fit into a variety of matteboxes which conform to ARRI R2 design standards.

The Tiffen MRT features three modes of operation in one filter tray: a rotating polarizer, variable ND (integrated with polarizer function, rotate gear to adjust ND value), and Warm/Cool FX filter effect. To achieve these different functions, add or remove the horizontal ND and/or simply reverse the tray in the mattebox filter stage (see detailed usage notes below). The MRT also has a unique ability to control contrast in Warm/Cool configuration when the camera is set to shoot in monochrome/B&W mode. 

Features:

  • Up to 6-stop (focal length dependent) of Tiffen VND (Variable Neutral Density) with M8 geared ring for ease of use, minimum of 2-stops.
  • Geared, 138mm, ultra thin Circular Polarizer for greater field of view (when used without combined 4x5.65 Circular Polarizer)
  • Patented, quick-release (removable) 4x5.65 ultra thin Circular Polarizer, when combined with a 138mm ultra thin geared Circular Polarizer, will produce a Variable ND or Cool to Warm FX color effect
  • Built into a single 6mm tray
  • Designed to be used with sunshades and matteboxes from ARRI, Bright Tangerine, Chrosziel, Movcam, TLS Optics, Vocas, TLS Optics, et al.
  • For detailed mattebox compatibility, visit http://tiffen.com/mrt-compatibility/
  • Geared adjustment for precision exposure, for control by hand or industry standard M8 gear wheel
  • Uses only one tray space in mattebox/clip-on sun shade, allowing the use of a second filter tray
  • Tray engravings provide easy positioning
  • Includes protective case
  • Quick reference guide included

Usage Notes:

  • To use the MRT as a Rotating Circular Polarizer ONLY:
    • Face the filter tray "A-SIDE" towards the lens.
    • Do not add the additional 4 x 5.65 Circular Polarizer.
  • To use the MRT as a Variable Neutral Density (VND) Filter:
    • Place the 4 x 5.65 filter into the (MRT) tray so that the engraving "FOR VND USE. THIS SIDE MUST FACE THE LENS" is readable.
    • Place the MRT into the mattebox/sun shade. The MRT will now function as a VND in this configuration.
    • You can now rotate the geared wheel to review.
    • Please use the Alpha markings on the gear ring and the engraved "+/-" on the "A-FACE" of the tray as a guide to increase or decrease the effect.
    • Please be advised that the amount of light reduction the MRT can cut is focal length dependent when configured as a VND filter.
    • Always check edge of frame for vignetting and, in extreme cases, for a dark cross in the center of your frame.
    • The best way to look for possible vignetting and uneven transmission in your image is to use a waveform monitor and a solid grey card; evenly illuminate the grey card making sure the card covers the entire image area of the lens.
    • Any uneven variance in light transmission will be visible on the monitor as you rotate the gear.
  • To use as a Warm/Cool FX Filter:
    • Place the 4 x 5.65 filter into the (MRT) tray so that the engraving "FOR WARM / COOL USE. THIS SIDE MUST FACE THE LENS" is readable.
    • Place the MRT into the mattebox/sunshade.
    • The MRT will now work as a WARM / COOL FX Filter in this configuration.
    • You can now rotate the geared wheel to review.
    • Please use the Alpha markings on the gear ring and the engraved "+/-" on the "A-FACE" of the tray as a guide to increase or decrease the effect.
