Size and weight are big decision factors when you are trying to find the ideal camera for your needs.

Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Canon A2300 is 20g lighter than the Canon A4000 IS but we don't think this will make a significant difference.
Weather Sealing
Unfortunately neither the Canon PowerShot A2300 nor Canon PowerShot A4000 IS 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 A4000 IS's 3.00" LCD screen is slightly larger than Canon A2300's 2.7" screen.
Unfortunately, both cameras has fixed screens so they don't tilt or flip in directions.
