OVF is great to use.
Colour is fabulous. Love the Velvia simulation.
Image quality excellent. Like putting a Leica lens on m4/3.
A few too many, "If you do this, you can't do this" scenarios. (Or user error, I'm not sure)
Well built. I think the one I saw at the Focus On Imaging show, was either battered or a prototype. This is a different thing altogether.
Did I say its complicated!
High ISO truly remarkable.
Not for beginners.
Handles really well.
Most fun I've had with a camera for years.
Maybe too many options, I personally would have liked it simpler.
