Unlike Olympus, Panasonic have been slow to produce converters for their lenses (unless their existence has somehow passed me by). Are they compatible with lenses other than the 200mm? It'd certainly be handy to have the option of boosting my 100-300mm lens although I'd guess it's too old to be compatible but what of the newer 100-400mm lens?
