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 MIII and Olympus E-M5 II side-by-side from the front, back and top in their relative dimensions. Canon G7 X MIII has external dimensions of 105 x 61 x 41 mm (4.13 x 2.4 x 1.61″) and weighs 304 g (0.67 lb / 10.72 oz) (including batteries). Olympus E-M5 II has external dimensions of 124 x 85 x 45 mm (4.88 x 3.35 x 1.77″) and weighs 469 g (1.03 lb / 16.54 oz) (including batteries).
Below you can see the front-view size comparison of the Canon G7 X MIII and the Olympus E-M5 II. Canon G7 X MIII is clearly the smaller of the two cameras. Its body is 19mm narrower, 24mm shorter and 4mm thinner than Olympus E-M5 II. As you can tell, actually this is not a fair size comparison since Canon G7 X MIII has a built-in lens but Olympus E-M5 II doesn't. Once you put a lens on E-M5 Mark II, its thickness will increase significantly.
Here is the back view size comparison of the Canon G7 X MIII and Olympus E-M5 II.
Now lets look at the top view comparison of Canon G7 X MIII and Olympus E-M5 II.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Canon G7 X MIII is significantly lighter (165g ) than the Olympus E-M5 II 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 E-M5 Mark II, the total kit will weigh much higher.
Weather Sealing
Thanks to the weather-sealed body of the E-M5 Mark II, 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 MIII.
LCD Screen Size and Features
Canon G7 X MIII and Olympus E-M5 II's LCD screens have the same diagonal size of 3.00 inches.
Canon G7 X MIII features a
Tilting-only screen which is mostly only good for shooting from waist or over-the-head levels. On the other hand, Olympus E-M5 II sports a
Fully Articulated screen which is more flexible and useful, especially for taking selfies and video.
