The K&F Concept Blue Streak filter is a coloured filter for camera lenses that adds blue transparent lines to the image, creating blur, gradients and distortion. Grinding and polishing on both sides of the lens help preserve image sharpness, while the 28-layer MRC coating reduces reflections and ghosting.
Its surface is resistant to water, mould, scratches and oil. The aviation-grade aluminium frame features a CNC-machined trapezoidal design for easier rotation, installation and removal, while its slim profile helps limit vignetting on wide-angle and telephoto lenses.
