I own a micro four-thirds Panasonic Lumix DMC-G7 mirrorless camera, and recently I purchased an old Olympus 40-150mm Zuiko ED Lens, which is not MFDMFT. Though this lens is listed as compatible with my camera on Panasonic's website, I need to buy an adapter for it since it is a simple four thirds lens. There are numerous MFDMFT-FD adapters on the internet, and I am not sure which are compatible with my specific requirements. Is there a particular adapter I should purchase for this, or will any FD-MFDMFT adapter work?
