Panasonic quietly announced the development of a Leica DG SUMMILUX 15mm F1.7 lens, which the company says will be an ideal companion to the DMC-GM1 also released today. Details are scarce at this point, but the lens (equivalent to 30mm on a Micro Four Thirds body) will have a manual aperture ring and will ship sometime next year. Also coming in 2014 are a Leica DG NOCTICRON 42.5mm F1.2 lens, as well as a budget-friendly Lumix G 35-100mm.
