I would like to upgrade my Panasonic LX-3 to something with a slightly larger sensor. 4/3 is the most likely contender, with Olympus and Panasonic models being most interesting. If you live in Nashville, own such a camera and wouldn’t mind letting my play with it for a couple of days, please let me know.
My other option would be to get the smallest Canon DSLR and use a small lens like 35/2 or 50/2.5 macro, but that would still be too large for the intended use. Local stores don’t carry much of a variety and playing with controls at the counter doesn’t really tell me much anyway.
Articulated LCD and physical controls instead of a touchscreen are preferred. Panasonic G2 looks like a likely contender, perhaps with a 45/1.8 lens. Anyone with direct experience with that or similar cameras?
