The Schneider 4 x 5.65" 3mm Red True-Streak Filter is designed to be used perpendicular to a point light source such as the sun, a light bulb, or a candle. Within the filter's glass is a combination of fine line types whose action is limited to point light sources. Upon those light sources, those lines create the effect of a scene or image that has been recorded with an anamorphic lens and then displayed using a complementary reverse projection lens. This can result in prominent, elongated streaks that are symmetric and extend horizontally from each point light source for the purpose of drawing attention to a specific part of the frame, or to create a visually dramatic effect.

If an image or footage is captured with an anamorphic lens for the primary purpose of obtaining a greater aspect ratio than what is possible when only using spherical lenses on a 35mm format, the direct result will appear compressed and distorted. Projecting this compressed and distorted footage or imagery through a reverse anamorphic projection lens allows elements within the scene to be viewed in their correct proportions. A complementary effect of this process after it is completed is the creation of elongated, blue-colored, horizontally symmetrical highlights from point light sources that can extend through the frame.

Many cinematographers and photographers find this effect desirable and the Schneider 4 x 5.65" 3mm Red True-Streak Filter is intended to allow such highlights to be easily reproduced when using optics that do not have an anamorphic design. This filter renders the streaks it helps to create with a red hue, instead of the blue highlights generated when using traditional anamorphic optics that are not designed to suppress streaking. True-Streak Filters that are formulated to create orange, yellow, green, blue, pink, or violet banding instead of red are also available, as well as Clear True-Streak Filters that can allow existing colors or lack of colors displayed by point light sources to be maintained.

The line types within this filter's glass are placed 3mm apart from each other. True-Streak Filters with spaces of 4mm, 2mm, or 1mm between their lines are also available where this filter type's effect becomes progressively stronger as the spacing between those lines is decreased.

This filter is most effective for pictures where the light source used to generate the streak effect is a highlight with a significant degree of contrast from the rest of the image. It is constructed from water white glass for clarity as well as color fidelity.

Related Questions and Answers

Q: 1. How do I use a 77mm lens with this matte box?

A: This matte box has 15mm rod support. With a lens of that size you would need to have the camera on a baseplate with 15mm rods.

Q: 2. Does this come with step down rings?

A: The Tilta MB-T12 does not come with step-down rings.

Q: 3. What are the thickness of the tray holders? Would it fit the Tiffen Multi Rota Tray Variable Neutral Density Kit? Thanks.

A: Tiffen has a compatibility chart up on their website for their Multi Rota Tray Products. This Matte Box is not listed on that page, it has yet to be tested with the Matte Box and it may not work properly.http://bit.ly/2eQHAgrWe do have some options that are listed on Tiffen's Compatibility from Bright Tangerine, Chrosziel and Vocas that you could look in to instead. They are B&H Numbers BRB12300012, CH41502F11 and VOMB455S.

Q: 4. What is the widest focal length you can use with this mattebox without vignetting?

A: Generally, with the Tilta MB-T12 114mm Matte Box and Carrying Case Kit, it is recommended not to go wider than a 24mm lens when working with a full-frame sensor and 16mm when working with a Super 35 or APS-C sensor.

Q: 5. What are the dimensions and depth from frame to lens mount?

A: We believe you are asking what is the distance from front to the back of the matte box. Our guesstimate would be about 4 /10cm.

Q: 6. Has anyone been able to use this with the Canon f/2 28-70mm RF lens?

A: The Tilta 3-Stage 4 x 5.65" Carbon Fiber Clip-On Matte Box (95mm Back) would not be able to be used with the Canon RF 28-70mm f/2 L USM Lens as it is designed to clamp onto cinema-style lenses.

Q: 7. I'm looking for a matte box to use on a Sony 200-600mm lens. Will this matte box work? I want to run a VND. Thanks!

A: Yes, the Tilta 3-Stage 4 x 5.65" Carbon Fiber Clip-On Matte Box (110mm Back) could work if you have 15mm rod mounts. However, you may want to consider the Tilta Mirage VND Matte-Box that would screw into the filter threads of your lens model. The Mirage comes with ring sizes up to 82mm. Tilta Mirage VND Kit BH #TIMBT16A

Q: 8. Is it possible to get with 80mm instead of 85mm?

A: The kit does come with an 80mm back. The description on the B&H website is incorrect -- the matte box comes with 80mm, 95mm, 114mm, 134mm backings.

Q: 9. Can one filter tray take two 2mm Formatt Hitech Firecrest Ultra Cine Superslim 4x5.65 IRND filters stacked together?

A: The Tilta 3-Stage 4 x 5.65" Carbon Fiber Clip-On Matte Box has three 4 x 5.65" Filter Trays. We can not advise stacking filters in a single tray.
