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 Pentax P70 and Canon ELPH 500 HS side-by-side from the front, back and top in their relative dimensions. Pentax P70 has external dimensions of 97 x 54 x 22 mm (3.82 x 2.13 x 0.87″) and weighs 155 g (0.34 lb / 5.47 oz) (including batteries).

Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Pentax P70 is significantly lighter (30g ) than the Canon ELPH 500 HS which may become a big advantage especially on long walking trips.
Weather Sealing
Unfortunately neither the Pentax Optio P70 nor Canon ELPH 500 HS (IXUS 310 HS / IXY 31S) 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 500 HS's 3.20" LCD screen is slightly larger than Pentax P70's 2.7 screen.
Unfortunately, both cameras has fixed screens so they don't tilt or flip in directions.
