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 ZS7 and Fujifilm Real 3D W3 side-by-side from the front, back and top in their relative dimensions. Panasonic ZS7 has external dimensions of 103 x 60 x 33 mm (4.06 x 2.36 x 1.3″) and weighs 218 g (0.48 lb / 7.69 oz) (including batteries). Fujifilm Real 3D W3 has external dimensions of 124 x 66 x 28 mm (4.88 x 2.6 x 1.1″) and weighs 230 g (0.51 lb / 8.11 oz) (including batteries).
Below you can see the front view size comparison of Panasonic ZS7 and Fujifilm Real 3D W3. Panasonic ZS7 is 21mm narrower and 6mm shorter than Fujifilm Real 3D W3 but it is also 5mm thicker.

Weight is another important factor especially when deciding on a camera that you want to carry with you all day.
Panasonic ZS7 is 12g lighter than the Fujifilm Real 3D W3 but we don't think this will make a significant difference.
Unfortunately neither Panasonic Lumix DMC-ZS7 (Lumix DMC-TZ10) nor Fujifilm FinePix Real 3D W3 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
Fujifilm Real 3D W3's 3.5" LCD screen is slightly larger than Panasonic ZS7's 3" screen.
