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 Efina and Nikon S70 side-by-side from the front, back and top in their relative dimensions. Pentax Efina has external dimensions of 87 x 54 x 21 mm (3.43 x 2.13 x 0.83″) and weighs 91 g (0.20 lb / 3.21 oz) (including batteries). Nikon S70 has external dimensions of 97 x 61 x 20 mm (3.82 x 2.4 x 0.79″) and weighs 160 g (0.35 lb / 5.64 oz) (including batteries).
Below you can see the front-view size comparison of the Pentax Efina and the Nikon S70. Pentax Efina is 10mm narrower and 7mm shorter than Nikon S70 but it is also 1mm thicker.
Here is the back view size comparison of the Pentax Efina and Nikon S70.
Now lets look at the top view comparison of Pentax Efina and Nikon S70.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Pentax Efina is significantly lighter (69g ) than the Nikon S70 which may become a big advantage especially on long walking trips.
Weather Sealing
Unfortunately neither the Pentax Efina nor Nikon Coolpix S70 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
Nikon S70's 3.50" LCD screen is slightly larger than Pentax Efina's 2.5" screen.
Unfortunately, both cameras has fixed screens so they don't tilt or flip in directions.
