Gee, just what the world really needs.
I wouldn't have thought that pot of gold at the end of the rainbow was big enough for the existing players.
I have no idea. I'll let those whose hobby is poring over annual reports, trying to divine sales figures, etc. chew on the question.
All these m4/3 companies may be wrong or maybe you are. I don't know.The Micro Four Thirds system, originally developed by Olympus and Panasonic, now lists Carl Zeiss, Astro Design, SVS-Vistek, Kenko Tokina, Cosina, Schneider-Kreuznach, JK Imaging, Tamron, View Plus, Photron and Blackmagic Designs as members. Sigma also makes lenses for the system.
Plus JVC Kenwood now.
