The Schneider 6.6x6.6" 4mm Red True-Streak Filteris 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 6.6 x 6.6" 4mm 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 4mm apart from each other. True-Streak Filters with spaces of 3mm, 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. can you use this filter with the blue snowball?

A: This stand has a 5/8'' thread and should screw into the bottom of the Snowball.

Q: 2. Will this work on a Sony a7R3?

A: The answer is technically yes. This lens will fit on your Sony but it's made to work on Sony APS-C/cropped sensor cameras. So if you put this on a full frame you're going to get a cropped sensor/APS-C framing and lower resolution.

Q: 3. Does this lens clear the grip (and fingers) on an E-M1 III?

A: No, a bit of crop in post is neccessary.

Q: 4. Is the base supposed to be wonky? All 4 feet do not rest on a level surface. Is this on purpose or did I get a lemon?

A: Of course this item should offer stable support. Please contaqct our customer service: B&H Customer Service Team: Call: 800.221.5743 or 212.239.7765 Email: cs@bhphotovideo.com

Q: 5. Will this work on Canon R or RP? I've noticed someone had problems with the R7. R and RP are older cameras. Can someone confirm?

A: While you will be able to mount and use the Venus Optics Laowa 4mm f/2.8 Fisheye Lens for Canon RF on the Canon EOS R and RP, it is not recommended. This lens is designed for APS-C cameras. This means you will see a significant vignette on the image.

Q: 6. Does this lens make a full circular image on a MFT sensor?

A: It is not quite a full circle. Please take a look at the sample images.

Q: 7. Is it compatible with BMPCC4K? In case not, is there any adaptor?

A: Yes. The Blackmagic Design Pocket Cinema Camera 4K, B&H # BL4KPKCAM, uses the Micro Four Thirds lens mount, and the Venus Optics Laowa 4mm f/2.8 Fisheye Lens for Micro Four Thirds uses the Micro Four Thirds lens mount, you may use the Venus Optics Laowa 4mm f/2.8 Fisheye Lens for Micro Four Thirds on the Blackmagic Design Pocket Cinema Camera 4K. Do note that the Venus Optics Laowa 4mm f/2.8 Fisheye Lens for Micro Four Thirds is a fully manual lens, so you would have to focus the lens manually and adjust the aperture of the lens using the aperture ring built onto the lens.

Q: 8. Is this compatible with Sony NEX-5N? without any extra accessory?

A: It is not. This is an MFT mount lens, it is not compatible with a Sony E-Mount camera.

Q: 9. Will this work with a Panasonic GH4? Or Panasonic S2?

A: This 7Artisans 4mm f/2.8 Circular Fisheye Lens for Micro Four Thirds can fit the Panasonic GH4. It does not work on the Panasonic S2.

Q: 10. Is there a version for RF?

A: No, the 7artisans Photoelectric 4mm f/2.8 Circular Fisheye Lens does not come in a RF version. Currently we have a 7artisans Photoelectric 4mm f/2.8 Circular Fisheye Lens for Canon EF-M.
