Does anyone know of any teleconverters that have been released for the :43: system? I have never seen or heard of any. The release of the Olympus 75mm lens prompted my question. As the 75mm focal length is not one that I would find terribly usable, it's highly unlikely that I will ever own this lens (particularly considering the price). For me, a 1.7x teleconverter along with the Olympus 45mm would be a more practical, flexible 75mm solution. I realize that I'd lose 1-2 stops of light with a teleconverter, so this combination would not be as fast as the 75mm lens, but I think it would be fast enough for my purposes. Olympus offers teleconverters for Four Thirds, so I wonder if this is something they (or an enterprising third party) is likely to ever offer for the :43: system?
