I don't have any problems with it as is, but there are definitely a few things I'd like to see improved anyway. I'd say Armando's #1 and #3 are the primary.
And Don, I'm not really lusting after anything out there right now either. BUT, the strengths of my various cameras have allowed me to create my own fictional "perfect camera" . It would more or less be an X100, with a Nex flip up screen and GH2 auto-focus. And, if sensor performance keeps improving, I think I'd like it with an GFD/LX5 sized sensor so I could use it in manual focus almost all the time and just hyperfocus or zone focus the thing into submission when I didn't want to use the GH2 quality AF. Then again, if it had a Nex screen AND great AF AND a silent shutter AND the OVF, I guess I wouldn't ever really need to shoot blindly so the small sensor and manual focus wouldn't add much....
So, no I'm not jonesing for anything at the moment, but someone will build that camera of mine someday and when they do, I will buy it. And if they could do with with interchangeable lenses in 24, 28, and 35mm focal length equivalents, I'd probably sell everything else except the GH2 to have some long lens and zoom capability.
I don't ask for much, really.
