Tiffen Multi Rotating Tray (MRT) with Circular Polariser Kit

The Tiffen Multi Rotating Tray (MRT) Base Unit with Circular Polariser Kit allows the use and rotation of a 138mm Circular Polariser (included) and a 4x5.65" Circular Polariser (included) simultaneously. When both filters are used together, it can be used as a variable Neutral Density (ND) filter (up to 6-stops) or to produce warm/cool colour effects. The tray is ideal for matte boxes that come without a rotating filter stage or when a secondary rotating filter stage is required in a non-rotating stage. It is compatible with a variety of matte boxes which conform to ARRI R2 design standards.

1. To use the MRT as a Rotating Circular Polarizer only:

Face the filter tray "A-SIDE" towards the lens. Do not add the additional 4X5.65 Circular Polarizer.

2. To use the MRT as a Variable Neutral Density (VND):

Place the "4X5.65" filter into the (MRT) tray so that the engraving "For VND use. This side must face the lens" is readable. Now place the MRT into the Matte Box / Sunshade. The MRT will now work 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, when set up as a VND is focal length dependent. Always check for 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 show up as you rotate the gear on the monitor.

3. To use as a Warm/Cool FX:

Place the 4x5.65" filter into the (MRT) tray so that the engraving "For warm/cool use. This side must face the lens" is readable. Now place the MRT into the Matte Box / Sunshade. The MRT will now work as a warm/cool FX 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.
