Unveiled: Panasonic Leica DG Summilux 12mm f/1.4 ASPH. Lens


Ultra-fast, ultra-wide, and built for professionals, the Panasonic Leica DG Summilux 12mm f/1.4 ASPH. Lens for Micro Four Thirds cameras is an ideal optic for demanding photographers and filmmakers who need maximum resolution and light gathering in a wide-angle prime. Designed for the fine detail of landscapes, and with a splash- and dustproof build for the more adventurous shooter, this lens offers a super-wide yet versatile 24mm equivalent focal length. Combine this field of view with a fast f/1.4 aperture, and photographers looking for a lightweight kit for their next trip will be more than satisfied.

To achieve such quality in a compact design, the 12mm uses two aspherical elements, which prevent spherical aberrations and distortion, as well as one extra-low dispersion and two ultra-extra-low dispersion elements to minimize chromatic aberrations and ensure clear imagery. Filmmakers will find this to be an excellent choice because it offers smooth aperture adjustments along with fast and silent autofocus. Also, the ability to capture fine details satisfies the demands of high-resolution 4K video recording.

For tactile, intuitive handling, this lens features a physical aperture ring on the lens barrel, along with a focusing ring and an AF/MF switch. In order to fit into the Micro Four Thirds ecosystem, this metal lens has been made quite compact, compared to DSLR equivalents. Additionally, it utilizes a circular nine-blade aperture to create smooth out-of-focus areas and comes with a dedicated metal lens hood and storage bag.
