Which micro four thirds camera should I buy?

For most people, I'd point you to the Olympus OM-D E-M1 Mark II. It's a weather-sealed pro body with fast autofocus and bursts, and it's still a capable used buy.

If you want something older, the Panasonic Lumix GH4 was the camera that brought 4K video to Micro Four Thirds. It has no stabilisation in the body, so it's better paired with stabilised lenses.

Every Micro Four Thirds lens fits both bodies, so the lens you choose matters more than the body. Read Micro Four Thirds for the system overview, and buying used before you spend anything.
