The Micro Four Thirds system has a pretty extensive lens lineup, but maintaining a collection can be an expensive hobby. Panasonic is providing a cheaper way to expand your photographic options, though, as long as you already own its Lumix G X 14-42mm zoom or G 14mm f/2.5 prime. The company has announced four converters that attach directly onto the front of a regular lens, effectively changing them into fisheye, wide angle, telephoto or macro optics. The wide angle lens attaches only to the 14mm f/2.5 and expands the field of view to 11mm (22mm equivalent), and the teleconverter doubles the 14-42mm zoom's focal length to reach 168mm equivalent. The macro and fisheye converters attach to either lens, and provide a roughly 14-centimeter minimal focusing distance and 120-degree field of view respectively. No official word yet on pricing or availability, but we wouldn't expect these to cost anywhere near as much as a dedicated fisheye or macro lens.
