Not lal of you probably know that some of the current Panasonic-Leica MFT lenses are actually designed by Konica:
Leica 45mm f/2.8 (patent here)
Leica 8-18mm f/2.8 (patent here)
Panasonic 150mm lens (patent here).
Well, I now spotted a brand new Konica patent that describes a 50-250mm f/4.5-5.8 lens. There may be a Panasonic lens with those specs coming? It could be a cheaper version of the soon to be released new Leica 50-200mm f/2.8-4.0
