Panasonic Leica DG Nocticron 42.5mm F1.2 ASPH OIS

Manufacturer description: The Panasonic Leica DG Nocticron 42.5mm / F1.2 ASPH. / Power O.I.S is a fast, stabilized portrait lens for the Micro Four Thirds system. The F1.2 maximum aperture makes it the brightest autofocus lens for the system and offers good control over depth-of-field for portrait work. It also offers low-light capability, supported by a Power O.I.S stabilization system that's been optimized to correct for the larger movements that are likely to occur during longer exposures. The lens features a complex 14 element/11 group design and includes a nano-scale coating to reduce flare and ghosting.
