The K&F Concept Nano-B Series Single Motion Blur Filter (77mm) is a creative special-effects lens filter designed for DSLR and mirrorless cameras with a 67mm filter thread. It is engineered to produce a directional motion blur effect on one side of the frame while preserving relative sharpness around the main subject area.
This single motion blur filter allows photographers to simulate movement, speed, and cinematic energy directly in-camera. It is particularly effective for portrait, street, sports-inspired compositions, and experimental visual storytelling where dynamic motion effects are desired without post-production editing.
Made from high-transmission optical glass, the filter maintains good clarity while applying a controlled directional blur gradient. The Nano-B Series coating helps reduce reflections, flare, and ghosting while maintaining balanced color reproduction across the image.
The rotatable slim aluminum alloy frame enables users to adjust the direction of the motion effect (horizontal, vertical, or angled), offering flexible creative control depending on composition and subject placement. Its slim design also helps reduce vignetting on wide-angle lenses.
