Weather Sealing
Unfortunately neither the Panasonic Lumix DMC-LF1 nor Panasonic Lumix DMC-LS5 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 LF1's 3.00" LCD screen is slightly larger than Panasonic LS5's 2.7 screen.
