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

Weather Sealing
Unfortunately neither Panasonic Lumix DMC-ZS3 (Lumix DMC-TZ7) nor Panasonic Lumix DMC-FZ35 (Lumix DMC-FZ38) provides any type of weather sealing in their body, so you have to give extra care especially when you are shooting outdoors.

LCD Screen Size and Features
Panasonic ZS3's 3" LCD screen is slightly larger than Panasonic FZ35's 2.7" screen.
Unfortunately, both cameras has fixed screens so they don't tilt or flip in directions.
