I used to use MMF-1 on my E-M5 for four third bundle lenses which I bought together with E-620 without any issues.

When I tried to use one of those bundle lenses on E-M1 ii, it would not work.

I thought that the contacts of the unit were contaminated but it would not work either after cleaning the contacts of the unit.

I checked the manual of E-M1 ii and found that only MMF-2 and MMF-3 are mentioned.

Is MMF-1 no longer supported by E-M1 mark ii or my unit is out of order?

I do not have the MMF-1, but the E-M1.1 manual says the same thing as the E-M1.2 manual. I would think there would have been a post long ago if this was a problem. I have MMF-3's on two lenses which work on either camera.

Don't push the button on the body when attaching the adaptor or on the adaptor when attaching the lens. If the adaptor still works on the E-M5, there could be a problem with the E-M1.2.

There was an old discussion where the consensus was they behaved identically:
FWIW, it is listed on this compatibility table:
I suspect that by the time the E-m1 mark I (and II) were announced, the MMF-1 had been officially retired in favor of the MMF-2, and it stopped being added to new lists.

Thank you for confirming the compatibility. It seems to be marketing strategy anyway. Will try again. Thanks.
 
Now, it works. I must have been loosely connecting to the mount or adapter without confidence. When I connected lens to the adapter by turning to the end, it works well. Still it is not very stable as the communication is once lost between the lens and the body and AF was converted to MF but even MF would not work. When I forced the lens to snugly fit to the adapter again, the problem was resolved. Thank you.

Thank you. I also thought it should work. Will try again following your advice of carefully attaching the lens and the adaptor.

I BELIEVE, the main (only?) difference between the MMF-1, which was the original adapter for four-thirds lenses and the Micro Four-Thirds system, and the later MMF-3 is the lack of the rubber seal on the MMF-1 to keep the weather sealing between body and lenses in-tact.

I figure that's one reason why Olympus stopped mentioning the MMF-1 in later materials.

I have both MMF1 and MMF3 adapters... With MMF1 I have had some connection problems, mostly with 12-60mm lens.

Anyway, I am quite sure those problems are caused by the wear and use. Usually reconnecting the adapter and lens solves the problem. Cleaning the contacts helps for a while too. And the MMF1 is anyway a backup solution now for me, so no big deal.

Cheers!
