dpreview lists G2 as being heavier than G1 (428g versus 360g). If this istrue then for me this is a disadvantage for G2. It starts bringing it closer to regular DSLRs.
Though I am not sure why G2 needs to be heavier than even GH1 (385g as per dpreview).
From the Panasonic website:
The G1 body weight without memory card and battery is 385g, the lens weighs 195g.
The G2 body weight without memory card and battery is 371g, and the new 14-42 lens weighs 165g
Dpreview sometimes can be as bad as Ken Rockwell :ROTFL:
