PolarPro’s new Center Split Filter delivers a split-field effect that keeps your subject sharp in the middle of the frame while blooming and diffusing detail above and below, aimed at stylized sequences that you want to capture in-camera rather than fake in post.  

This is not a new optical concept in itself, but PolarPro packages it in a rugged, modern housing with their Cinema Series glass and several mounting options. If you like building distinctive looks on set, this is a simple way to introduce a dreamlike, music-video style aesthetic without complex rigs or compositing.

What the filter does

The Center Split Filter creates a split-field style image: crisp focus in the center band, with increasingly diffused detail toward the top and bottom of frame. PolarPro positions it as a creative effect that is difficult to replicate authentically in editing software, and one that lends itself to transitions, fashion, lifestyle, and portrait work.

Recommended focal lengths and apertures

PolarPro and independent reporting suggest the effect shows best between 35 mm and 85 mm at wide apertures from around f/2.8 to f/1.4. At 35 mm, more of the optical element enters the frame, so refraction and edge distortion are stronger. At 85 mm the look is subtler and more controlled.

Build and mounting options

The filter uses PolarPro’s Cinema Series glass with multi-layer anti-scratch and anti-reflective coatings in a CNC-machined, matte-black aluminum frame. It is available as a standard threaded filter and for the Helix MagLock ecosystem. Threaded sizes include 67 mm, 77 mm, and 82 mm, with a 49 mm option also listed. A microfiber pouch is included.

Use cases on set

This is a niche tool, but it can be very effective for dream sequences, experimental transitions, or to add an in-camera surreal layer to music videos and fashion spots. If you prefer to commit to a look during production and save time in finishing, the Center Split approach delivers a consistent, repeatable result without the complexity of diopter stacks or post distortion passes.

Not a replacement for your everyday glass

PolarPro and reviewers frame this as a specialty filter. It is designed to complement a standard kit, not to live on the lens all day, and it will reward deliberate framing where your subject sits in the central sharp band.

Pricing and availability

Listed prices at launch are 49 mm at 79.99 US dollars, 67/77/82 mm at 99.99 US dollars, and Helix at 149.99 US dollars.
