Micro four thirds lens and camera compatibility

I was looking at some micro four thirds camera to buy. I am not too sure how the whole system works:

• Can I use four thirds lens on micro four thirds camera? And the opposite?



• What brands make micro four thirds/four thirds cameras?

Answer

You can use a Micro Four-Thirds lens on a Micro Four-Thirds camera and they are compatible between manufacturers, so Zuiko, Olympus, Panasonic, Leica, Sigma and Samyang lens are all compatible with cameras from Olympus and Panasonic as long as the mounts are Micro Four-Thirds.

You can use a Four-Thirds lens on a Micro Four-Thirds camera with an adapter which must be purchased separately. There are a few options but if you have a weather-sealed Micro Four-Thirds camera and a weather-sealed Four-Thirds lens, you must buy the Weather-Sealed adapter from Olympus to keep the whole system weather-sealed.

It is NOT possible to put a Micro Four-Thirds lens on a Four-Thirds camera because it needs to be mounted closer to the sensor than possible for it to focus properly.
