How about build-in EVF that can be tilted?I don't think m 4/3 is at it's best yet. First thing that needs improvement is high ISO performance probably 16-18 clean (not noisy at high ISO) megapixels would be optimum.
I think the perfect camera would be the size of the new Sony NEX, High ISO performance like a Nikon D3s, Shoot video like a Canon 5D MKII, have controls of a Canon I DS MK IV, have lens quality of Leica M lenses, lens selection of combined Nikon and Canon DSLR collections and for the price of an Olympus E-PL1.
And IS/IBIS as well as AF support via adapter for non-native lenses?
Next to these two features, body-wise I would actually be satisfied with just gradual improved High ISO and dynamic range over GF1 in LX3 sized body with incorporated L1 flash.
- Instead of going after the pro-level camera, to my opinion Panasonic should look more at out of camera JPG (noise reduction, motion blur detection, panorama sweep like Sony, HDR like LX3) and lens selection (or have Sigma/Tamron enter the m43 market) for easy access to better photography for less experienced people (biggest market).
