Material
Precious high-reflective and low-dispersion glass material including lanthanum is abundantly used to correct diverse aberrations at very high level.

Brightness
High transmission multi-coating* over all the air-contacting lens surfaces in combination with special coating on the lens connecting surfaces deliver surprisingly high contrast and bright field of view.

Compatibility

Design
The sturdy anodized aluminum body harmonizes with luxury color variation design arranged in order of a length of wavelength and focal length. (Ex. Violet = short wavelength = short focal length)
