Panasonic Leica Summilux DG 12mm f/1.4 ASPH Review

The Leica DG Summilux 12mm f/1.4 ASPH lens from Panasonic is a fast, high-performance prime lens built for the micro four thirds system. With the full frame equivalent focal length of 24mm and a wide maximum aperture of f/1.4, this lens is built to capture low-light scenes and, if you focus close enough, a shallow depth of field.
