Questions & Answers

Shopper : Does this cause any change in focal length, focusing distance, or amount of light hitting the sensor?DAVID P : No, it just allows oldLADONNA A : With the Olympus you get a much smaller "package" of camera and lenses, easier to carry. Sharp and detailed prints. Downside, it is not full frame so low light is a problem. If you can live with that it's great!TOM A : I never noticed any changes in focal length,focusing distance, or loss of light with this adapter. I use it on Olympus Macro lens. However on my Panasonic GX8 the focusing is slow which I believe is normal.KENNETH J : None of the above parameters are modified.BURTON A : Not that I'm aware of.Diane D : I am not an expert, but I have not noticed any difference. Works fine.RICHARD M : I don't think the adapter has any effect on the 3 things you mention. It allows me to use my old Four Thirds lenses on a Micro Four Thirds camera (E-M1) and it works well.
Jacob J : Will this work on Panasonic cameras? If so, does it allow in-camera aperture control of Olympus lenses?JURGEN K : presumably "yes" ... but is meant to use the old 4/3's lenses , the Zuiko digital SLR lenses with the newer MICRO 4/3s cameras, so yes, all functions carry over.... that's why this is so expensive!!
Shopper : WILL THIS ADAPTER WORK WITH M-1O 11 ?EDWARD D : It should work perfectly to adapt your regular digital lenses to the micro-four thirds format. I additionally used an adapter to go from analog to digital and then to micro-four thirds so I could use my 180m f/2 analog film lens! A really nicely made adapter!CARL H : I am unaware of an M 10 11.

Saved the glass!

Didn't want to give up my Olympus lenses when my camera died... the only option was to purchase another Olympus but would need an adapter to use my lenses... I hesitated, was this the time to switch systems? With thousands invested in Olympic equipment, I decided used to take a chance and purchase the new Olympus but this adapter was crucial to the operation... and it is stellar... the camera performance is wicked good and this part makes it possible! Best Camera money I have ever spent.

Glad I went with Olympus

There are many cheaper alternatives to this adaptor but Olympus has a design to excell over the others in this field. It fits like a glove, has an easy quick removal system for battery access, and looks like part of the original camera design. Adorama's price was not beat by anyone and delivery was fast.

I had a 510 until I dropped it and replace with a 620

I had a 510 until I dropped it and replace with a 620. I purchased an EM-1 body only. I had a large investment in lens. The MMF-3 Alound me to use my Zuiko lens. I also own a M-10. I own several M-Zudio lens 150 or less. My 300-600 is usable with the MMF13.

Pricey, but Fits

Pricey, but adapter fits my EM-1 perfectly and allows me to use 4/3 lenses that were not available in the micro 4/3 mount.

Great adapter

Use this with Ollympus 4/3 lenses. Does a very good job of adapting these lenses to newer format. Great build quality, and since native adapter, no problems with interface. As time has gone by and I have bought more micro 4/3 lenses, I am using this less often.

Lovely combination

Good price works as it should and enabled me to use my 50-200 Olympus SWD on the EM1. Lovely combination

Essential Addition for Four Thirds Lens Folks

This adapter is exactly what was needed from Olympus, now having officially migrated over the micro four thirds format. Some functionality is lost (the 81 point focus points, for ex), but to regain use of legacy lenses, it's a small price. Weather sealing is an added bonus!

Works perfectly

Works great with my OMD-1 and FT lenses. Only reason I gave it 4 out of 5 stars is that the price seems rather high for an adapter.

Great product!

This adapter makes using all of my old four thirds lenses possible! A must have for anyone that has a collection of those lenses that they want to use with the new micro four thirds system.

Does what it says

This is an adapter for using older E-1 through E-5 Zuiko Digital lenses on the E-M1. It works fine with all of my 4/3 lenses and does what it says.

Does what it needs to.

It bridges the gap that Olympus created when it stopped making E series cameras. Allows the use of all my pro quality 43 lenses on Pen size m43 bodies when I want to travel light. The only concern I have is balance and weight issues on the adapter and Pen body with the larger and heavier glass attached.

Solid fit for 4/3 lenses

Although not cheap the excellent fit provides better results than the cheap aftermarket adapters. If you invest in high quality lenses don't lose their performance due to a loose fitting adapter.

Can now use my 4/3 lenses

Enjoying using my Olympus 12-60 and 70-300 lenses with my OMD5 and EM1. A really nice viewfinder that's easy for me to see what I'm photographing unlike my E-620. Sometimes takes a while to get sharp focus. Don't now how good that would be with moving subjects. Haven't tried that yet. However, I'm definitely keeping it.

Functional but costly

This certainly does the job, but Olympus charges a premium for essentially adding a tiny o-ring to the adapter. Fittings are all metal.

Range Expander

I started using digital capture with Olympus products because they did not cobble a digital camera from an existing 35mm body. They came out with a new design for their product. That being the case, I have a lot of 4/3 lenses. This adapter lets me use the 4/3 lenses on my micro 4/3 camera.

It fits like a glove, has an easy quick removal system for battery access, and looks like part of the original camera design. Adorama's price was not beat by anyone and delivery was fast.

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. 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.
