Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.

Weather Sealing
Unfortunately neither the Panasonic Lumix DMC-LX7 nor Panasonic Lumix DMC-FH20 (Lumix DMC-FS30) 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
Panasonic LX7's 3.00" LCD screen is slightly larger than Panasonic FH20's 2.7" screen.
Unfortunately, both cameras has fixed screens so they don't tilt or flip in directions.
