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 SZ-10 and Panasonic ZS45 side-by-side from the front, back and top in their relative dimensions. Olympus SZ-10 has external dimensions of 106 x 67 x 38 mm (4.17 x 2.64 x 1.5″) and weighs 215 g (0.47 lb / 7.58 oz) (including batteries). Panasonic ZS45 has external dimensions of 108 x 60 x 32 mm (4.25 x 2.36 x 1.26″) and weighs 249 g (0.55 lb / 8.78 oz) (including batteries).
Below you can see the front-view size comparison of the Olympus SZ-10 and the Panasonic ZS45. Panasonic ZS45 is 7mm shorter and 6mm thinner than Olympus SZ-10 but it is also 2mm wider.
Here is the back view size comparison of the Olympus SZ-10 and Panasonic ZS45.
Now lets look at the top view comparison of Olympus SZ-10 and Panasonic ZS45.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Olympus SZ-10 is 34g lighter than the Panasonic ZS45 but we don't think this will make a significant difference.
Weather Sealing
Unfortunately neither the Olympus SZ-10 nor Panasonic Lumix DMC-ZS45 (Lumix DMC-TZ57) 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 SZ-10 and Panasonic ZS45's LCD screens have the same diagonal size of 3.00 inches.
On the other hand, Panasonic ZS45 features a
Tilting screen where you can change the angle of the screen to make it easier to shoot from waist or over-the-head levels whereas the Olympus SZ-10 has a fixed type screen which provides less flexibility in shooting positions compared to ZS45.
