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 Pentax RZ18 and Olympus SH-50 side-by-side from the front, back and top in their relative dimensions. Pentax RZ18 has external dimensions of 97 x 61 x 33 mm (3.82 x 2.4 x 1.3″) and weighs 178 g (0.39 lb / 6.28 oz) (including batteries). 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).

Here is the back view size comparison of the Pentax RZ18 and Olympus SH-50.
Now lets look at the top view comparison of Pentax RZ18 and Olympus SH-50.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Pentax RZ18 is significantly lighter (91g ) than the Olympus SH-50 which may become a big advantage especially on long walking trips.
Weather Sealing
With its weather-sealed body, we believe that the RZ18 has a big advantage over the SH-50 which doesn't provide any kind of environmental sealing.
LCD Screen Size and Features
Pentax RZ18 and Olympus SH-50'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.
