K&F Concept 49mm Blue Streak Filter KF01.2094

Blue Streak Filter Effects

The blue streak filter produces cool brushed effects by adding a layer of blue transparent lines to the image. This creates blur, gradient, deformation, and other visual effects, enhancing the artistic and visual appeal of movies or photos.

Optical Quality

• Both sides of the lens undergo grinding and polishing technology to ensure ultra-high definition.
• This process balances the light penetration trajectory, preserving image sharpness without degradation.

Advanced Coatings

• Features a 28-layer anti-reflection coating to effectively reduce surface reflections and prevent ghosting.
• The surface is coated with a high-tech film providing mouldproof, waterproof, scratch-resistant, and oil-resistant properties.

Frame Design and Material

• The frame surface has a CNC trapezoidal pattern to increase friction, facilitating easy rotation and installation/removal of lenses and accessories.
• Constructed from aviation-grade aluminum with a slim 5.3mm thickness.
• The thin frame design prevents vignetting on both wide-angle and telephoto lenses.
