Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Canon SX400 IS is 17g lighter than the Nikon A1000 but we don't think this will make a significant difference.
Weather Sealing
Unfortunately neither the Canon PowerShot SX400 IS nor Nikon Coolpix A1000 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
Canon SX400 IS and Nikon A1000's LCD screens have the same diagonal size of 3.00 inches.
On the other hand, Nikon A1000 features a
Tilting screen where you can change the angle of the screen to make it easier to shoot from waist or over-the-head levels whereas the Canon SX400 IS has a fixed type screen which provides less flexibility in shooting positions compared to A1000.
