· F1.4 brightness allowing a beautiful soft focus for photos and videos to be even more impressive

· A superb image quality with minimum distortion, chromatic aberrations that pass a stringent Leica standard

· The UHR (Ultra High Refractive) index lens and glass mold aspherical lenses for achieving uniformed description from the center to the edges

· Panasonic's Nano Surface Coating technology minimizes reflection at the entire visual light range (380nm-780nm) by applying the extra-low refractive index coating with nano-sized structure on the surface of the lens. It results in super clear pictures with dramatic reduction of ghost and flare.

· Circular aperture diaphragm

·  Durable metal mount
