⚡ At a Glance
  • Image Quality: Layered motion blur preserves a clear central subject while adding streaked, dreamlike highlights
  • Best for: Landscape, portrait and creative photographers wanting in-camera special effects
  • Not ideal for: Work that demands clinically sharp results or high-speed sports capture

Handheld semicircular kaleidoscope filter produces motion blur and psychedelic effects in-camera. High-transmittance K9 optical glass maintains accurate colour and reduces stray light.


Dreamlike Motion Effects – With semicircular kaleidoscope design

A semicircular prism element sits over the lens and can be shifted during exposure; changing angle and position alters streak direction and intensity in real time. The handheld format lets the effect be introduced selectively across the frame.

Adds vintage, psychedelic and abstract character straight from the camera, cutting down on post-production. Works well for staged portraits and sweeping landscapes where atmosphere matters.

High-Fidelity Colour and Clarity – With K9 optical glass

K9 optical glass delivers high light transmittance and strong colour reproduction, while a special surface treatment helps prevent stray light from degrading the image. Optical-grade construction minimises imperfections and unwanted artefacts.

Preserves natural colours and clear midtones even with heavy visual effects. Keeps images looking intentional rather than simply blurred.

Real-Time Creative Control – Thanks to handheld adjustment

Handheld semicircular format allows continuous repositioning while tracking a subject, so blur can be intensified or softened without stopping the shoot. Angle and distance adjustments provide a wide range of visual outcomes.

Enables spontaneous variation and subject tracking during live shoots, ideal for dynamic sessions and experimental work. Useful when immediate in-camera results are preferable to editing later.
