Weather Sealing
Unfortunately neither the Panasonic Lumix DMC-FH3 (Lumix DMC-FS11) nor Ricoh GXR P10 28-300mm F3.5-5.6 VC provides any type of weather sealing in their bodies, so you have to give extra care especially when you are shooting outdoors.

LCD Screen Size and Features
Ricoh GXR P10 28-300mm's 3.00" LCD screen is slightly larger than Panasonic FH3's 2.7" screen.
Unfortunately, both cameras has fixed screens so they don't tilt or flip in directions.
