50mm (35mm camera equiv.) LEICA DG SUMMILUX 25mm / F1.4 ASPH. (H-X025)

Features

  • 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
