Tiffen Ser.9 Star 4pt 4mm Lens Filter

The Tiffen Series 9 4-Point Star Filter (with 4mm spacing) is a specialized optical effects filter designed to transform bright point-light sources into distinct, four-pointed starbursts. As an unthreaded Series 9 filter (measuring 3.25 inches in diameter), it is designed to be dropped directly into a matte box tray, a lens hood, or a dedicated Series 9 retaining ring.

Because standard cinema lenses naturally render bright lights as soft glowing orbs or unpredictable optical flares, cinematographers looking to add a highly stylized, glamorous, or retro aesthetic to concert footage, music videos, or nighttime cityscapes need a physical filter to actively shape the light. The 4-Point Star filter solves this by utilizing a precise grid of microscopically etched lines across the glass surface. This specific 4mm version features wider spacing between those lines, which helps prevent the overall image from becoming too washed out or overly cluttered with stars, allowing you to add that classic theatrical flair without destroying the underlying contrast of the shot.
