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 S1 and Fujifilm S4500 side-by-side from the front, back and top in their relative dimensions. Pentax S1 has external dimensions of 114 x 58 x 28 mm (4.49 x 2.28 x 1.1″) and weighs 157 g (0.35 lb / 5.54 oz) (including batteries). Fujifilm S4500 has external dimensions of 118 x 81 x 100 mm (4.65 x 3.19 x 3.94″) and weighs 543 g (1.20 lb / 19.15 oz) (including batteries).

Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Pentax S1 is significantly lighter (386g ) than the Fujifilm S4500 which may become a big advantage especially on long walking trips.
Weather Sealing
Unfortunately neither the Pentax Optio S1 nor Fujifilm FinePix S4500 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
Fujifilm S4500's 3.00" LCD screen is slightly larger than Pentax S1's 2.7" screen.
Unfortunately, both cameras has fixed screens so they don't tilt or flip in directions.
