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 SX50 HS and Panasonic G7 side-by-side from the front, back and top in their relative dimensions. Canon SX50 HS has external dimensions of 123 x 87 x 106 mm (4.84 x 3.43 x 4.17″) and weighs 595 g (1.31 lb / 20.99 oz) (including batteries). Panasonic G7 has external dimensions of 125 x 86 x 77 mm (4.92 x 3.39 x 3.03″) and weighs 410 g (0.90 lb / 14.46 oz) (including batteries).
Below you can see the front-view size comparison of the Canon SX50 HS and the Panasonic G7. Panasonic G7 is 1mm shorter and 29mm thinner than Canon SX50 HS but it is also 2mm wider. As you can tell, actually this is not a fair size comparison since Canon SX50 HS has a built-in lens but Panasonic G7 doesn't. Once you put a lens on G7, its thickness will increase significantly.
Here is the back view size comparison of the Canon SX50 HS and Panasonic G7.
Now lets look at the top view comparison of Canon SX50 HS and Panasonic G7.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Panasonic G7 is significantly lighter (185g ) than the Canon SX50 HS which may become a big advantage especially on long walking trips.
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 G7, the total kit will weigh much higher.
Weather Sealing
Unfortunately neither the Canon PowerShot SX50 HS nor Panasonic Lumix DMC-G7 provides any type of weather sealing in their bodies, so you have to give extra care especially when you are shooting outdoors.
