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 SH-50 and Panasonic ZS40 side-by-side from the front, back and top in their relative dimensions. Olympus SH-50 has external dimensions of 112 x 63 x 42 mm (4.41 x 2.48 x 1.65″) and weighs 269 g (0.59 lb / 9.49 oz) (including batteries). Panasonic ZS40 has external dimensions of 111 x 64 x 34 mm (4.37 x 2.52 x 1.34″) and weighs 240 g (0.53 lb / 8.47 oz) (including batteries).
Below you can see the front-view size comparison of the Olympus SH-50 and the Panasonic ZS40. Panasonic ZS40 is 1mm narrower and 8mm thinner than Olympus SH-50 but it is also 1mm taller.
Here is the back view size comparison of the Olympus SH-50 and Panasonic ZS40.
Now lets look at the top view comparison of Olympus SH-50 and Panasonic ZS40.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Panasonic ZS40 is 29g lighter than the Olympus SH-50 but we don't think this will make a significant difference.
Weather Sealing
Unfortunately neither the Olympus SH-50 nor Panasonic Lumix DMC-ZS40 (Lumix DMC-TZ60) 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 SH-50 and Panasonic ZS40'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.
