Converts a Canon FD lens to a micro43 mount for use on Olympus and Panasonic m43 cameras. I have up to six of these adapters available. They come with an Olympus end cap for the m43 end which is convenient assuming you will need one for your FD lens. I've found these adapters to be the best ones for this combination. Cost is $10 per adapter and $5 for shipping (flat shipping rate for however many adapters you buy).
