Size and weight is a big decision factor when you are trying to find the ideal camera for your needs.
In this section, We are going to illustrate Nikon S70 and Canon ELPH 340 HS side-by-side from the front, back and top in their relative dimensions. 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). Canon ELPH 340 HS has external dimensions of 100 x 58 x 22 mm (3.93 x 2.27 x 0.88″) and weighs 147 g (0.32 lb / 5.19 oz) (including batteries).
Below you can see the front view size comparison of Nikon S70 and Canon ELPH 340 HS. Nikon S70 is 3mm narrower and 2mm thinner than Canon ELPH 340 HS but it is also 3mm taller.
Here is the back view size comparison of Nikon S70 and Canon ELPH 340 HS.
Now lets look at the top view comparison of Nikon S70 and Canon ELPH 340 HS.
Weight is another important factor especially when deciding on a camera that you want to carry with you all day.
Canon ELPH 340 HS is 13g lighter than the Nikon S70 but we don't think this will make a significant difference.
Unfortunately neither Nikon Coolpix S70 nor Canon PowerShot ELPH 340 HS (IXUS 265 HS) provides any type of weather sealing in their body, so you have to give extra care especially when you are shooting outdoors. If weather sealing is a must-have feature for you, check these sections: Top Compact Cameras with Weather Sealing
LCD Screen Size and Features
Nikon S70's 3.50" LCD screen is slightly larger than Canon ELPH 340 HS's 3" screen.
Unfortunately, both cameras has fixed screens so they don't tilt or flip in directions.
