Characterized by its fast and sophisticated optical design, the Leica DG Nocticron 42.5mm f/1.2 ASPH. POWER O.I.S. from Panasonic is an 85mm equivalent prime for Micro Four Thirds mirrorless cameras. The fast f/1.2 maximum aperture benefits working in difficult lighting conditions and also affords more control over focus position for producing shallow depth of field imagery. The lens's optical design employs a pair of aspherical elements, one UHR element, and one extra-low dispersion element to reduce both spherical and chromatic aberrations for improved sharpness and clarity. Additionally, a Nano Surface Coating also enhances contrast and color fidelity by reducing lens flare and ghosting.
Complementing the optical attributes, this lens also distinguishes itself with a POWER Optical Image Stabilizer, which minimizes the appearance of camera shake for sharper handheld shooting. A stepping AF motor and internal focus design also offer fast and near-silent focusing performance that is ideal for both photo and video applications.
