Features:

The Olympus MMF-3 Four Thirds Mount Adapter is a dust - and splashproof lens mount adapter makes it possible to mount any existing Four Thirds lens on a Micro Four Thirds standard-compliant digital camera, including Olympus OM-D Series and Olympus PEN Series models.

Due to its weathersealing, this adapter is preferable to the earlier MMF-2 and MMF-1 if you will be shooting in inclement or uncertain weather. It is ideal for getting the most value out of your weathersealed and Super High Grade Four Thirds-compliant lenses.

AF shooting using Live View is possible with lenses featuring contrast AF compatibility. When a contrast AF incompatible lens is used, the AF assist function engages.
