Have just bought the current OM-D camera from Olympus and have tested it against my professional Olympus E-5, and I am pleased to report it shall replace it. The image stabilisation (and true 1080p HD) for filming and gaining 3 to 4 stops is excellent news. Already have my first image accepted on Dreamstime using the new camera.
I opted for the packaged 12-50mm lens and apart from some obvious CA (correctable in post processing in RAW) on wide angle / contrasty backgrounds it's silent zoom is great for video shooting and a good all rounder for mobility.
New sensor is bigger at 16MP and with the adapter all my 4 thirds lenses fit too.
The weight and scale of it means its a take away holiday camera and not an encumbrance.
Really happy with it as my first camera way back at art college was an OM10!
