The Schneider 4x5.65" 4mm Orange 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 4 x 5.65" 4mm Orange 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 an orange 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 red, yellow, green, blue, pink, or violet banding instead of orange 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.

Q: 1. 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: 2. Does this lens make a full circular image on a Fujifilm X sensor?

A: This won't work on Fuji. You will need this lens that has a Fuji X mount. It does create a circular image on Fuji X sensor. https://www.bhphotovideo.com/c/product/1542241-REG/venus_optics_ve428fx_laowa_4mm_f_2_8_fisheye.html

Q: 3. What is the best enlarger lens to print 35mm negatives on a Beseler 4x5 enlarger?

A: A 50mm Schneider or Rodenstock lens would be most useful.

Q: 4. will the grip on my a6400 clear the immage with this lens?

A: Yes. The following lens is designed and made to accommodate E -Mount Lens/APS-C Format.

Q: 5. Would it be possible to adapt this to C mount? The focal length is wide enough that it sounds great for C mount super 8mm cameras. Do you have adapters from any of these mount options to C? And would the flange be off?

A: Unfortunately, we do not have any lens mount adapters designed to connect a lens designed for the Canon EF-M lens mount onto a camera that uses the C-mount lens mount.

Q: 6. Can I zoom in to get rid of vignetting (black corners) with this lens on a nikon z30?

A: The Venus Optics Laowa 4mm f/2.8 Fisheye Lens for Nikon Z is a lens with a fixed focal length of 4mm, so you cannot zoom in with this lens.

Q: 7. how would this lens perform on a FX Z mount?

A: Venus Optics Laowa 4mm f/2.8 Fisheye Lens for Nikon Z will work on an FX Z mount camera. However since it is an apsc lens the circular image will be very small in the frame. You can crop in later but the resolution will be much lower.

Q: 8. 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: 9. 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: 10. will this lens fit my Panasonic Lumix G85 ?

A: Yes, the Venus Optics Laowa 4mm f/2.8 Fisheye Lens for Micro Four Thirds lens will fit Panasonic Lumix G85.
