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 150 IS and Sony H70 side-by-side from the front, back and top in their relative dimensions. Canon ELPH 150 IS has external dimensions of 95 x 57 x 24 mm (3.74 x 2.24 x 0.94″) and weighs 142 g (0.31 lb / 5.01 oz) (including batteries). Sony H70 has external dimensions of 102 x 58 x 29 mm (4.02 x 2.28 x 1.14″) and weighs 194 g (0.43 lb / 6.84 oz) (including batteries).

Now lets look at the top view comparison of Canon ELPH 150 IS and Sony H70.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Canon ELPH 150 IS is significantly lighter (52g ) than the Sony H70 which may become a big advantage especially on long walking trips.
Unfortunately neither the Canon PowerShot ELPH 150 IS (IXUS 155) nor Sony Cyber-shot DSC-H70 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
Sony H70's 3.00" LCD screen is slightly larger than Canon ELPH 150 IS's 2.7" screen.
Unfortunately, both cameras has fixed screens so they don't tilt or flip in directions.
