Size and weight is a big decision factor when you are trying to find the ideal camera for your needs.
In this section, We are going to illustrate Panasonic FX48 and Canon SD970 IS side-by-side from the front, back and top in their relative dimensions. Panasonic FX48 has external dimensions of 95 x 53 x 22 mm (3.74 x 2.09 x 0.87″) and weighs 150 g (0.33 lb / 5.29 oz) (including batteries). Canon SD970 IS has external dimensions of 96 x 57 x 26 mm (3.78 x 2.24 x 1.02″) and weighs 160 g (0.35 lb / 5.64 oz) (including batteries).
Below you can see the front view size comparison of Panasonic FX48 and Canon SD970 IS. Panasonic FX48 is clearly the smaller of the two cameras. Its body is 1mm narrower, 4mm shorter and 4mm thinner than Canon SD970 IS.
Weight is another important factor especially when deciding on a camera that you want to carry with you all day.
Panasonic FX48 is 10g lighter than the Canon SD970 IS but we don't think this will make a significant difference.
Unfortunately neither Panasonic Lumix DMC-FX48 (Lumix DMC-FX40) nor Canon PowerShot SD970 IS / Digital IXUS 990 IS provides any type of weather sealing in their body, so you have to give extra care especially when you are shooting outdoors.

Canon SD970 IS's 3" LCD screen is slightly larger than Panasonic FX48's 2.5" screen.
