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 Canon ELPH 520 HS and Canon ELPH 530 HS side-by-side from the front, back and top in their relative dimensions. Canon ELPH 520 HS has external dimensions of 87 x 54 x 19 mm (3.43 x 2.13 x 0.75″) and weighs 155 g (0.34 lb / 5.47 oz) (including batteries). Canon ELPH 530 HS has external dimensions of 86 x 54 x 20 mm (3.39 x 2.13 x 0.79″) and weighs 163 g (0.36 lb / 5.75 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 520 HS is 8g lighter than the Canon ELPH 530 HS but we don't think this will make a significant difference.
Weather Sealing
Unfortunately neither the Canon ELPH 520 HS (IXUS 500 HS) nor Canon PowerShot ELPH 530 HS (IXUS 510 HS) 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 ELPH 530 HS's 3.20" LCD screen is slightly larger than Canon ELPH 520 HS's 3" screen.
Unfortunately, both cameras has fixed screens so they don't tilt or flip in directions.
