Panasonic has announced two new L-Mount lenses. The LUMIX S PRO 16-35mm f/4 is a new ultra-wide angle lens, and the LUMIX S PRO 70-200mm f/2.8 O.I.S. is a new fast version of the standard telephoto lens. Both lenses feature a rugged dust-, splash- and freeze-resistant construction, and a clutch mechanism to switch between auto and manual focus.
