Introduced last week, Panasonic's 12mm F1.4 brings a weather-resistant, fast 24mm equivalent prime to the Micro Four Thirds system. The Leica name on the lens is reflected in its sturdy metal build, its aperture control ring and its $1300 price tag. We intend to do much more shooting with the 12mm F1.4, including some architectural work, but for now here are some initial samples.
