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 Panasonic XS1 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). Panasonic XS1 has external dimensions of 94 x 54 x 14 mm (3.7 x 2.13 x 0.55″) and weighs 103 g (0.23 lb / 3.63 oz) (including batteries).

Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Panasonic XS1 is significantly lighter (75g ) than the Pentax RZ18 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 XS1 which doesn't provide any kind of environmental sealing.
LCD Screen Size and Features
Pentax RZ18's 3.00" LCD screen is slightly larger than Panasonic XS1's 2.7" screen.
Unfortunately, both cameras has fixed screens so they don't tilt or flip in directions.
