From the Panasonic website: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).
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:
