I have a Panny G3 and have just bought an Olympus 70-300 4/3 lens and adapter. I went to the Olympus website and there are some firmware updates for this lens. Naturally the updates all refer to Olympus cameras. My question is whether or not I can or should download Olympus firmware, and will my G3 be able to install the updates? I read somewhere that a lens can actually be rendered inoperable if the firmware update doesn't install properly. Obviously I don't want to take that kind of chance.
