Size and weight is a big decision factor when you are trying to find the ideal camera for your needs.
In this section, We are going to illustrate Panasonic ZS3 and Fujifilm Real 3D W1 side-by-side from the front, back and top in their relative dimensions. Panasonic ZS3 has external dimensions of 103 x 60 x 33 mm (4.06 x 2.36 x 1.3″) and weighs 229 g (0.50 lb / 8.08 oz) (including batteries). Fujifilm Real 3D W1 has external dimensions of 124 x 68 x 26 mm (4.88 x 2.68 x 1.02″) and weighs 260 g (0.57 lb / 9.17 oz) (including batteries).

Weight is another important factor especially when deciding on a camera that you want to carry with you all day.
Panasonic ZS3 is 31g lighter than the Fujifilm Real 3D W1 but we don't think this will make a significant difference.
Unfortunately neither Panasonic Lumix DMC-ZS3 (Lumix DMC-TZ7) nor Fujifilm FinePix Real 3D W1 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

Panasonic ZS3's 3" LCD screen is slightly larger than Fujifilm Real 3D W1's 2.8" screen.
