By now most of our readers know one of the most loved parts of Camera Decision: the Camera and Lens Size Comparison Tool. We keep adding new gear daily, and the latest are the OM System 50-200mm F2.8 IS PRO for Micro Four Thirds and the Panasonic S 100-500mm f5-7.1 O.I.S. for Leica L mount. In the side-by-side view, the 100-500mm looks surprisingly compact, which is impressive on its own (Compare Panasonic vs Canon 100-500mm Lenses).
