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 115 IS side-by-side from the front, back and top in their relative dimensions.

Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.

Weather Sealing
Unfortunately neither the Nikon Coolpix A10 nor Canon Elph 115 IS (IXUS 132 HS) provides any type of weather sealing in their bodies, so you have to give extra care especially when you are shooting outdoors.

Canon Elph 115 IS's 3.00" LCD screen is slightly larger than Nikon A10's 2.7 screen.
