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-100 and Panasonic FZ70 side-by-side from the front, back and top in their relative dimensions. Olympus SP-100 has external dimensions of 122 x 91 x 133 mm (4.8 x 3.6 x 5.25″) and weighs 594 g (1.31 lb / 20.95 oz) (including batteries). Panasonic FZ70 has external dimensions of 130 x 97 x 118 mm (5.12 x 3.82 x 4.65″) and weighs 606 g (1.34 lb / 21.38 oz) (including batteries).
Below you can see the front-view size comparison of the Olympus SP-100 and the Panasonic FZ70. Olympus SP-100 is 8mm narrower and 6mm shorter than Panasonic FZ70 but it is also 15mm thicker.
Here is the back view size comparison of the Olympus SP-100 and Panasonic FZ70.
Now lets look at the top view comparison of Olympus SP-100 and Panasonic FZ70.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Olympus SP-100 is 12g lighter than the Panasonic FZ70 but we don't think this will make a significant difference.
Weather Sealing
Unfortunately neither the Olympus Stylus SP-100 nor Panasonic Lumix DMC-FZ70 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-100 and Panasonic FZ70's LCD screens have the same diagonal size of 3.00 inches.
Unfortunately, both cameras has fixed screens so they don't tilt or flip in directions.
