K&F Concept 77mm Blue Streak Filter KF01.2101

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 are ground and polished using advanced technology to ensure ultra-high definition.
• This process balances the light penetration path, preserving image sharpness without degradation.

Coatings and Surface Treatment

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

Frame Design

• 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 to prevent vignetting on wide-angle and telephoto lenses.
