Weather Sealing
Unfortunately neither Panasonic Lumix DMC-ZS1 (Lumix DMC-TZ6) nor Panasonic Lumix DMC-FX78 (Lumix DMC-FX77) provides any type of weather sealing in their body, so you have to give extra care especially when you are shooting outdoors. If weather sealing is a must-have feature for you, check these sections: Top Compact Cameras with Weather Sealing
LCD Screen Size and Features
Panasonic FX78's 3.5" LCD screen is slightly larger than Panasonic ZS1's 2.7" screen.
Unfortunately, both cameras has fixed screens so they don't tilt or flip in directions.
