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

Panasonic ZS7 has external dimensions of 103 x 60 x 33 mm (4.06 x 2.36 x 1.3″) and weighs 218 g (0.48 lb / 7.69 oz) (including batteries).

Now lets look at the top view comparison of Panasonic ZS7 and Canon ELPH 530 HS.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Canon ELPH 530 HS is significantly lighter (55g ) than the Panasonic ZS7 which may become a big advantage especially on long walking trips.
Weather Sealing
Unfortunately neither the Panasonic Lumix DMC-ZS7 (Lumix DMC-TZ10) 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 Panasonic ZS7's 3" screen.
Unfortunately, both cameras has fixed screens so they don't tilt or flip in directions.
