Weather Sealing
Unfortunately neither Panasonic Lumix DMC-ZS1 (Lumix DMC-TZ6) nor Samsung ST100 provides any type of weather sealing in their body, so you have to give extra care especially when you are shooting outdoors.

Samsung ST100's 3.5" LCD screen is slightly larger than Panasonic ZS1's 2.7" screen.
