Olympus, Panasonic, and Sigma, the makers of Four Thirds cameras and lenses, have joined forces to make updating lens firmware easier. They have launched an online firmware update service that will enable people to update the firmware in their Four Thirds lens, even if the lens and camera are made by different manufacturers. Because lens and body mounting information in the Four Thirds system is based on an open standard, photographers can freely mix and match camera bodies and lenses supplied by participating manufacturers. Before lens firmware could only be updated if the lens was mounted on a camera by the same make, so an Olympus lens could only be updated if it were on an Olympus camera. This new service makes it possible to update the firmware of an Olympus lens even if it is mounted on a Panasonic camera, or a Sigma lens could be updated if mounted on an Olympus camera.
This service launched yesterday and more information can be found here.
