So, just popped into JL in the Trafford Centre and had a play with both. Both are lovely cameras and not a hugely massive size difference in the flesh, but the Lumix is definitely not pocket material (the flash is, thankfully, detachable):
So, first up the Sony, definitely small
But also slightly awkward for my sized hands
To get to the back buttons on the right hand side moved the camera away from my palm and therefore had the camera in my finger tips almost, which really affected by grip
The Lumix is a bit bigger
but felt a lot more sturdy in my hand and generally more comfortable maneuvering round the dials and buttons
There were a few other niggles with the Sony such as the EVF having to be pulled up and away from the body and not sitting "right" when I took the camera to my eye (although, admittedly, that could be my face rather than the camera's fault
)
After having a play, even with the higher cost of the Lumix and larger size it just felt "better" in my hands so I think we may have a winner, so now its just a case of black or silver !
Thanks all again for your input
cheers
