Weight is another important factor especially when deciding on a camera that you want to carry with you all day.
Panasonic ZS3 is 26g lighter than the Fujifilm XF1 but we don't think this will make a significant difference.
Weather Sealing
Unfortunately neither Panasonic Lumix DMC-ZS3 (Lumix DMC-TZ7) nor Fujifilm XF1 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
