Simple OMD versus GH3.

The sensor are not the same I think, (I was told by a Panasonic Lumix guy that are not equal.) look at the different low ISO.

Panasonic Lumix GH3

• GH3 ISO range (extended to 125 + 25600)ISO 
• OMD range (Lowest ISO200)

Simplicity is the ultimate sophistication.
God always take the simplest way.
Imagination is more important than knowledge.
God is the tangential point between zero and infinity.
