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 SX130 IS and Panasonic GF7 side-by-side from the front, back and top in their relative dimensions. Canon SX130 IS has external dimensions of 113 x 73 x 46 mm (4.45 x 2.87 x 1.81″) and weighs 308 g (0.68 lb / 10.86 oz) (including batteries). Panasonic GF7 has external dimensions of 107 x 65 x 33 mm (4.21 x 2.56 x 1.3″) and weighs 266 g (0.59 lb / 9.38 oz) (including batteries).
Below you can see the front-view size comparison of the Canon SX130 IS and the Panasonic GF7. Panasonic GF7 is clearly the smaller of the two cameras. Its body is 6mm narrower, 8mm shorter and 13mm thinner than Canon SX130 IS. As you can tell, actually this is not a fair size comparison since Canon SX130 IS has a built-in lens but Panasonic GF7 doesn't. Once you put a lens on GF7, its thickness will increase significantly.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Again, this comparison may not be very useful in real life as we are comparing the weight of a camera with a built-in lens to the body-only weight of an interchangeable lens camera. Once you put a lens on GF7, the total kit will weigh much higher.
Weather Sealing
Unfortunately neither the Canon PowerShot SX130 IS nor Panasonic Lumix DMC-GF7 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 SX130 IS and Panasonic GF7's LCD screens have the same diagonal size of 3.00 inches.
On the other hand, Panasonic GF7 features a
Tilting screen where you can change the angle of the screen to make it easier to shoot from waist or over-the-head levels whereas the Canon SX130 IS has a fixed type screen which provides less flexibility in shooting positions compared to GF7.
