Designed for Micro Four Thirds mirrorless cameras, the Panasonic Leica DG Summilux 9mm f/1.7 ASPH. Lens is a close-focusing wide-angle prime ideally suited for landscapes, cityscapes, and close-up scenes. Featuring a unique half-macro design, this lens offers a minimum focusing distance of just 3.7", making it an excellent choice for photographing and filming everything from close-ups of plants and small details to street scenes and vistas. Optimized for video as well as stills, the lens provides smooth and near-silent autofocus performance to complement movie recording applications, and the lens is also compatible with micro-step aperture control, which enables smooth exposure changes while recording video.
Boasting an outstanding optical design, this lens is comprised of twelve elements in nine groups, which include two aspherical elements to maintain a compact form factor and reduce spherical aberrations and distortions. Additionally, two extra-low dispersion elements and one ultra-high refractive index element work to minimize color fringing and chromatic aberrations for increased color fidelity and edge-to-edge sharpness. A rounded seven-blade diaphragm contributes to a pleasing out-of-focus quality when using selective focus techniques, and the lens also offers a weather-resistant design to protect the optics during heavy field use and harsh conditions.
