99% of the time my Sony RX100 never leaves its widest 28mm focal length, so I must be one of the 1%. If I need to get closer, I just move closer rather than use the zoom, so I pretty much use it like I did my GRD III as a fixed lens camera anyway so the Sony may as well not even have a zoom.
Anyway, at 245g the GR is roughly the same size and weight as the RX100, but with most of the Sony's weight being in the glass and mechanism of the zoom lens it's fairly front-heavy for such a little camera so the GR with its lighter fixed lens should balance a lot better when handling I think.
