The 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. Because of 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.

With the MMF-3 Four Thirds lenses can be connected to the outstandingly small Micro Four Thirds mount. Now also being dust and splash-proof the MMF-3 is perfect for the E-M5 and pro or top pro Four Thirds lenses, which are also dust and splash-proof and therefore perfect for all weather conditions. It is possible to use the whole range of Four Thirds lenses with a Mirco Four Thirds body* and this only with an adapter with a weight of 42g.

*If a ZUIKO DIGITAL lens is used, which is incompatible to high-speed contrast AF it is recommended to shoot in the "S-AF+MF" mode and adjust if it is necessary.

Customer Reviews of the MMF-3 Four Thirds Adapter

A must have for old E-system users with an OM-D E-M1

My E series lenses work beautifully with my E-M1 now that I have this adapter. My 50-200 works better than it did on my native E system. Focusing is fast and more precise. It is not as fast as the micro lenses but allows for the effective use of that wonderful E-system glass. This adapter has delayed my purchase of the new 40-150 2.8 lens. I know focusing is better and all reports are great but I cannot give up the 50-200 when it works this well.

Fantastic and weather sealed

Fantastic build quality. Works outstanding with 50mm Macro, and EM-1. Focus is quicker then on my E-3 with this set up. A+++ Must have if you have any Weather Sealed 4/3 lenses.

Works as described

Bought this converter to continue using my 4/3 lenses with a new micro 4/3 OM-D E-M1 body. The converter works as described, and the older lenses operate perfectly with the new camera body, including autofocus, etc.

Must have!

Can't believe how expensive these are but you have to get one if you have some four thirds lens laying around. Quality Olympus product.
