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 A10 but we don't think this will make a significant difference.
Weather Sealing
Unfortunately neither Nikon Coolpix A10 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
Canon ELPH 340 HS's 3.00" LCD screen is slightly larger than Nikon A10's 2.7" screen.
Unfortunately, both cameras has fixed screens so they don't tilt or flip in directions.
