Ive got a G1 bought it over a year ago. Its nice, got kit lens and 20mm pancake.
But Panasonic glass isnt cheap – it is good though. Do you really want to be commited to that or this system. Which system? That is important.
Does the camera have to be small?
The NEX-5 is probably the best small interchangable camera right now.
Olympus seems to be very good value, and in-body stabilisation is a nice feature. Good for legacy lenses.
With all these cameras you should be able to mount other lenses using adapters from ebay.
Im not sure I want to invest any more in this system (Panasonic). I am damn tempted to move over to Pentax.
The K-x possibly to tide me over until the K-5 drops in price. Currys are currently flogging the K-x with the 18-55mm Zoom Lens & 50-200mm Zoom Lens for 400 quid. Insane deal. Reduced by 230 quid. effectively a free lens. Or maybe I should just go nuts and buy a K-5 😈
