The Leica DG Summilux 25mm f/1.4 II ASPH. from Panasonic is a 50mm equivalent prime for Micro Four Thirds mirrorless cameras. Characterized by its fast f/1.4 maximum aperture, this lens affords notable control over depth of field and is also well-suited to working in low-light conditions. Its optical design incorporates one UHR element and a pair of aspherical elements to reduce spherical aberrations and distortion, and a Nano Surface Coating has also been applied to suppress lens flare and ghosting for greater contrast in harsh lighting. Normal-length prime is designed for Micro Four Thirds mirrorless cameras and provides a 50mm equivalent focal length. One UHR element and a pair of aspherical elements help to achieve even illumination and sharpness for consistent performance throughout the aperture range. Stepping AF motor, along with an internal focusing design, provides quick, smooth, and near-silent focusing performance to benefit both stills and video use. A rounded seven-blade diaphragm produces a smooth out-of-focus quality when working with shallow depth of field techniques.
