While maintaining the resolution, it leads to a cinematic and analog-like expression. Softening the light while maintaining resolution. Diffusion Glass is optical glass that slightly diffuses light, creating a natural lingering effect in its spread. To be able to build on the depiction of high-resolution cameras and lenses, the surface accuracy has been maximized, creating a state where both resolution and the softness of light can be felt simultaneously. Supporting resolution with quiet transmission. Nano AR Coating is an ultra-low reflection coating applied to suppress reflections on the glass surface and stabilize light transmission. Based on the depiction of high-resolution cameras and lenses, it suppresses unnecessary reflections and clouding of contrast, creating a state where the gradation of light and detailed information are naturally conveyed. Light does not overly assert itself, and the image rises while maintaining clarity. Supporting everyday use with water-repellent and anti-stain coating The water-repellent and anti-stain coating applied to both sides of the filter makes it easy to keep the glass surface clean.
