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 G7 X MII and Nikon D7100 side-by-side from the front, back and top in their relative dimensions. Canon G7 X MII has external dimensions of 106 x 61 x 42 mm (4.17 x 2.4 x 1.65″) and weighs 319 g (0.70 lb / 11.25 oz) (including batteries). Nikon D7100 has external dimensions of 136 x 107 x 76 mm (5.35 x 4.21 x 2.99″) and weighs 765 g (1.69 lb / 26.98 oz) (including batteries).
Below you can see the front-view size comparison of the Canon G7 X MII and the Nikon D7100. Canon G7 X MII is clearly the smaller of the two cameras. Its body is 30mm narrower, 46mm shorter and 34mm thinner than Nikon D7100. As you can tell, actually this is not a fair size comparison since Canon G7 X MII has a built-in lens but Nikon D7100 doesn't. Once you put a lens on D7100, its thickness will increase significantly.
Here is the back view size comparison of the Canon G7 X MII and Nikon D7100.
Now lets look at the top view comparison of Canon G7 X MII and Nikon D7100.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Canon G7 X MII is significantly lighter (446g ) than the Nikon D7100 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 D7100, the total kit will weigh much higher.
Weather Sealing
Thanks to the weather-sealed body of the D7100, you can use this camera with more confidence under conditions where there is risk of exposure to water and dust compared to the G7 X MII.
LCD Screen Size and Features
Nikon D7100's 3.20" LCD screen is slightly larger than Canon G7 X MII's 3 screen.
On the other hand, Canon G7 X MII LCD screen has a
Tilting feature where you can change the angle of the screen to make it easier to shoot from waist or over-the-head levels. On the other hand, Nikon D7100 has a fixed type screen which provides less flexibility in shooting positions compared to G7 X MII.
