Weather Sealing
Unfortunately neither the Ricoh CX6 nor Panasonic Lumix DMC-FX78 (Lumix DMC-FX77) provides any type of weather sealing in their bodies, so you have to give extra care especially when you are shooting outdoors.

Panasonic FX78's 3.50" LCD screen is slightly larger than Ricoh CX6's 3" screen.
