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 Panasonic FH25 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).

Weather Sealing
Unfortunately neither the Canon PowerShot ELPH 150 IS (IXUS 155) nor Panasonic Lumix DMC-FH25 (Lumix DMC-FS35) provides any type of weather sealing in their bodies, so you have to give extra care especially when you are shooting outdoors.

Canon ELPH 150 IS and Panasonic FH25's LCD screens have the same diagonal size of 2.70 inches.
