This is one rumor that has actually come good. Panasonic has officially launched the Leica DG Summilux 12mm f/1.4 ASPH lens designed for the micro four-thirds systems. Because of the 2x crop factor of micro-four third systems, this lens will have an effective focal length of 24mm.
At f/1.4 the lens would provide beautiful out of focus effects for those selective focusing attempts. Something that is only going to be accentuated by the rounded 9-blade aperture diaphragm. However, the ultra-wide angle lens with its wide angle of view, 84 ˚ to be precise, is ideally suitable for landscapes and architecture. Portraits would be a far cry for this baby.
There are a total of 15 elements in the lens arranged in 12 groups. The Leica DG Summilux 12mm f/1.4 ASPH is a designed to last. It is a splash proof and dust proof design. In other words this should be the ideal foil for a weather sealed micro four-thirds system cameras. This is a heavy design as the overall weight of the lens is 335 grams.
