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 Olympus SP-820UZ and Panasonic FZ150 side-by-side from the front, back and top in their relative dimensions. Olympus SP-820UZ has external dimensions of and weighs 485 g (1.07 lb / 17.11 oz) (including batteries). Panasonic FZ150 has external dimensions of 124 x 82 x 92 mm (4.88 x 3.23 x 3.62″) and weighs 528 g (1.16 lb / 18.62 oz) (including batteries).
Below you can see the front-view size comparison of the Olympus SP-820UZ and the Panasonic FZ150. Olympus SP-820UZ is 7mm narrower and 4mm shorter than Panasonic FZ150 but it is also 1mm thicker.
Now lets look at the top view comparison of Olympus SP-820UZ and Panasonic FZ150.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Olympus SP-820UZ is 43g lighter than the Panasonic FZ150 but we don't think this will make a significant difference.
Weather Sealing
Unfortunately neither the Olympus Stylus SP-820UZ nor Panasonic Lumix DMC-FZ150 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
Olympus SP-820UZ and Panasonic FZ150's LCD screens have the same diagonal size of 3.00 inches.
On the other hand, Panasonic FZ150 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. Olympus SP-820UZ's LCD screen is a fixed type which provides almost no flexibility in shooting positions compared to FZ150.
