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 Panasonic FZ100 and Panasonic FZ40 side-by-side from the front, back and top in their relative dimensions. Panasonic FZ100 has external dimensions of 124 x 82 x 92 mm (4.88 x 3.23 x 3.62″) and weighs 540 g (1.19 lb / 19.05 oz) (including batteries). Panasonic FZ40 has external dimensions of 120 x 80 x 92 mm (4.72 x 3.15 x 3.62″) and weighs 494 g (1.09 lb / 17.43 oz) (including batteries).
Below you can see the front-view size comparison of the Panasonic FZ100 and the Panasonic FZ40. Panasonic FZ40 is 4mm narrower and 2mm shorter than Panasonic FZ100 but they have the same thickness of 92mm.

Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Panasonic FZ40 is 46g lighter than the Panasonic FZ100 but we don't think this will make a significant difference.
Weather Sealing
Unfortunately neither the Panasonic Lumix DMC-FZ100 nor Panasonic Lumix DMC-FZ40 (Lumix DMC-FZ45) provides any type of weather sealing in their bodies, 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 Bridge Cameras with Weather Sealing
LCD Screen Size and Features
Panasonic FZ100 and Panasonic FZ40's LCD screens have the same diagonal size of 3.00 inches.
On the other hand, Panasonic FZ100 sports a
Fully Articulated screen which you can change the angle and position of the screen almost freely, making it possible to shoot from waist or over-the-head levels, and especially very useful for shooting selfies and video. Panasonic FZ40's LCD screen is a fixed type which provides almost no flexibility in shooting positions compared to FZ100.
