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 Panasonic FZ70 and Canon SX40 HS side-by-side from the front, back and top in their relative dimensions. Panasonic FZ70 has external dimensions of 130 x 97 x 118 mm (5.12 x 3.82 x 4.65″) and weighs 606 g (1.34 lb / 21.38 oz) (including batteries). Canon SX40 HS has external dimensions of 123 x 92 x 108 mm (4.84 x 3.62 x 4.25″) and weighs 600 g (1.32 lb / 21.16 oz) (including batteries).
Below you can see the front-view size comparison of the Panasonic FZ70 and the Canon SX40 HS. Canon SX40 HS is clearly the smaller of the two cameras. Its body is 7mm narrower, 5mm shorter and 10mm thinner than Panasonic FZ70.
Here is the back view size comparison of the Panasonic FZ70 and Canon SX40 HS.
Now lets look at the top view comparison of Panasonic FZ70 and Canon SX40 HS.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Canon SX40 HS is 6g lighter than the Panasonic FZ70 but we don't think this will make a significant difference.
Weather Sealing
Unfortunately neither the Panasonic Lumix DMC-FZ70 nor Canon PowerShot SX40 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
Panasonic FZ70's 3.00" LCD screen is slightly larger than Canon SX40 HS's 2.7 screen.
