Olympus OM-D E-M5 Camera or Nikon D7000?

I know they are very different camera's used for different purposes.
But what are your opinions?
For about the same price is the Olympus really worth it?

Olympus aren't really worth, nikon cameras are way better! I have been going on classes for almost 3 years and everyone knows the nikon are way better if you want really Professional photos the olympus are more like 'to go'

An Olympus E(volt) DSLR would make it a fair contest.
I'd choose the Pentax K-30 over the D7000, either way, but a DSLR is a better camera than any EVIL will ever be.

Go for Nikon D7000 with the best features.

In my opinion neither. Instead, look at the Pentax K-30. Its the only camera in its price range that has a weather-sealed camera body and kit lens.

NOTE: "Weather-sealed" should NOT be confused with "water proof". Weather-sealed simply means its safe to use the camera in a light rain or in very dusty conditions.
