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 1D X II and Panasonic G7 side-by-side from the front, back and top in their relative dimensions. Canon 1D X II has external dimensions of 158 x 168 x 83 mm (6.22 x 6.61 x 3.27″) and weighs 1530 g (3.37 lb / 53.97 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 1D X II and the Panasonic G7. Panasonic G7 is clearly the smaller of the two cameras. Its body is 33mm narrower, 82mm shorter and 6mm thinner than Canon 1D X II.
Here is the back view size comparison of the Canon 1D X II and Panasonic G7.
Now lets look at the top view comparison of Canon 1D X II 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 (1120g ) than the Canon 1D X II which may become a big advantage especially on long walking trips.
Also keep in mind that body weight is not the only deciding factor when comparing two interchangeable camera bodies, you also have to take into account the lenses that you will be using with these bodies. Since Canon 1D X II has a Full frame sensor and Panasonic G7 has a smaller Four Thirds sensor, Panasonic G7's lenses for a similar focal length and aperture will generally be lighter and smaller than the Canon 1D X II lenses.
Weather Sealing
With its weather-sealed body, we believe that the 1D X MII has a big advantage over the G7 which doesn't provide any kind of environmental sealing.
LCD Screen Size and Features
Canon 1D X II's 3.20" LCD screen is slightly larger than Panasonic G7's 3 screen.
