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 Nikon A10 and Canon ELPH 150 IS side-by-side from the front, back and top in their relative dimensions. Nikon A10 has external dimensions of 96 x 59 x 29 mm (3.78 x 2.32 x 1.14″) and weighs 160 g (0.35 lb / 5.64 oz) (including batteries). Canon ELPH 150 IS has external dimensions of 95 x 57 x 24 mm (3.74 x 2.24 x 0.94″) and weighs 142 g (0.31 lb / 5.01 oz) (including batteries).

Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Canon ELPH 150 IS is 18g lighter than the Nikon A10 but we don't think this will make a significant difference.
Weather Sealing
Unfortunately neither the Nikon Coolpix A10 nor Canon PowerShot ELPH 150 IS (IXUS 155) 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 A10 and Canon ELPH 150 IS's LCD screens have the same diagonal size of 2.70 inches.
