Four Thirds system users who have multiple manufacturer systems such as a Panasonic/Leica Four Thirds lens on an Olympus dSLR will now be able to update the firmware on their lens even though it is not the same brand as the camera.
This is an important development, particularly, as we can expect some lens firmware upgrades to improve compatibility with the Micro Four Thirds cameras.
