GH2's outstanding versatility is enhanced by Micro Four-Thirds system capability to use a vast range of legacy lenses of many makes with adapter mounts. Picture shows one such useful combination: a 40-year-old 500mm f/8 Reflex-Nikkor mounted with Voigtländer F mount adapter - becoming a very handy manual focus, fixed aperture 1000mm (35mm equivalent) f/8 lens.
