Size and weight are big decision factors when you are trying to find the ideal camera for your needs.
In this section, we are going to illustrate the Fujifilm F900EXR and Panasonic 3D1 side-by-side from the front, back and top in their relative dimensions. Fujifilm F900EXR has external dimensions of 105 x 61 x 36 mm (4.13 x 2.4 x 1.42″) and weighs 232 g (0.51 lb / 8.18 oz) (including batteries). Panasonic 3D1 has external dimensions of 108 x 58 x 24 mm (4.25 x 2.28 x 0.94″) and weighs 193 g (0.43 lb / 6.81 oz) (including batteries).

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

Weather Sealing
Unfortunately neither the Fujifilm FinePix F900EXR nor Panasonic Lumix DMC-3D1 provides any type of weather sealing in their bodies, so you have to give extra care especially when you are shooting outdoors.

LCD Screen Size and Features
Panasonic 3D1's 3.50" LCD screen is slightly larger than Fujifilm F900EXR's 3" screen.
