The 138mm 4pt/4mm Star Filter from Tiffen creates multiple points of light, or "stars," streaking outward from a central light source.  This filter comes in a rotating mount for critical placement of the star effect.

 Wedding photographers will especially appreciate the value of this filter. When it comes to special effects shots, why not offer your client a table shot of the menu or invitation next to a glowing, star-filled candle? Shooting at night? Make that street lamp take on a different, more dramatic appearance by using the star filter. Any point light source will achieve the effect.

Tiffen's ColorCore glass is produced through a process that entails permanently laminating the filter material in between two pieces of optical glass that are ground flat to tolerances of a ten-thousandth of an inch, then mounting them in precision aluminum rings.

Creates a Streaking Pattern    Use With Point Light Source    Rotating    Black Aluminum Filter Ring    ColorCore Glass    Made in the USA    10-Year Warranty

The effect is produced by a series of thin lines etched into the flat optical surface of a clear filter

The size and brightness of the star lines produced are first a function of the size, shape, and brightness of the light source: You have additional control through the choice of a particular spacing between the lines on the filter

These spacings are measured in millimeters and range from 1mm to 4mm: A 1mm spacing has twice as many lines as a 2mm spacing and will produce a brighter star for any given source

Lines in one direction produce a two-pointed star, just a streak through the center of the light

Tiffen offers 4, 6, and 8 point symmetrical star effects as well as additional asymmetrical star patterns through their exclusive Hollywood FX Series (North, Hyper, Vector and Hollywood star effects)

Tiffen's ColorCore glass is sealed between two optical glass sheets. In this way, Tiffen can better control the various densities of their filters and thereby create more exact degrees of filtration. This process makes for greater accuracy of color as opposed to glass that is simply dyed and become subject to deviation during the dye process

Tiffen, a leader in the filter industry, proudly makes its filters in the USA and backs up its products with a solid 10-year warranty

Related Questions and Answers

Q: 1. Does this modifier do the same as a scoop with a grid on it?

A: If you are referring to a light scoop as a device that provides indirect lighting, then no, the above modifier would not work as a light scoop. Light scoops are typically angled in front of a light source to prevent light from directly striking your subject, therefore, providing indirect lighting to illuminate your subject. A grid is designed to be connected to a light source and aimed directly at your subject for extremely directional, focused lighting (similar to a spot light). Grids are not used for indirect lighting; as they block light from heading in any direction other than straight from the source, they are extremely directional and must be aimed directly at the subject to be lit.

Q: 2. Does this grid system fit Canon's 600ex-rt?

A: I don't have a canon 600 flash, but it fits all of my flashes (580 ex ll, vivitar 285s, canon 430 ex ll, and magnum flashes).

Q: 3. do this lens work fine with fx3 and fx6 full frame cameras?

A: The Venus Optics Laowa 4mm f/2.8 Fisheye Lens for Sony E will work on a full frame camera but it will only produce a small circle in the frame. It is made for use with a crop sensor.

Q: 4. Compatible with Canon EL-1 Speedlite?

A: The Photoflex RapiDome with Grid Kit is compatible with the Canon EL-1 Speedlite.

Q: 5. Which mattebox works with theses lenses? So the mattebox is not visible in the picture?

A: It is not recommended to use a matte box with the Venus Optics Laowa 4mm f/2.8 Fisheye Lens for Canon RF because with the amount of fisheye that this lens has, the matte box will be in the frame. The same thing will happen with a lens hood as well.

Q: 6. any issues with the stand it comes with?

A: No, the stand is lightweight yet sturdy and the tightening knobs are well made.

Q: 7. What does this come with? Do I need to buy a softbox seperate? or this is just honeycomb?

Q: 9. Does this lens clear the grip (and fingers) on an E-M1 III?

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

Q: 10. Will it work with a remote trigger like a PocketWizard or do you need another mount for the receiver on the light stand?

A: Depending on the trigger you are using you can put the trigger under the flash or you could use a shoe extension bar like this one to put it beside the flash. https://bhpho.to/2IbcVwN
