Things I don't like.
The control dial:
- no lock to prevent it turning in your pocket
- no physical index "bump" to feel where it's at
The rear controls:
- the macro button doesn't select macro
... press left button [..] and then Info and then left/right to select the focus mode
And that's about it.
It's a minor annoyance that on wide angle you can see the flash is shaded by the VF-2.
But operating in remote control flash mode makes up for it when I put my Metz 58 AF-2 in slave mode. A very powerful combination.
I don't carry the 1D bodies every day, or the GH-1 or the E-P1.
Maybe the camera that you can carry with you that you use is your best camera ...
