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 Olympus E-M1 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). Olympus E-M1 has external dimensions of 130 x 94 x 63 mm (5.13 x 3.68 x 2.48″) and weighs 497 g (1.10 lb / 17.53 oz) (including batteries).
Below you can see the front-view size comparison of the Canon G7 X MII and the Olympus E-M1. Canon G7 X MII is clearly the smaller of the two cameras. Its body is 24mm narrower, 33mm shorter and 21mm thinner than Olympus E-M1. As you can tell, actually this is not a fair size comparison since Canon G7 X MII has a built-in lens but Olympus E-M1 doesn't. Once you put a lens on E-M1, its thickness will increase significantly.
Here is the back view size comparison of the Canon G7 X MII and Olympus E-M1.
Now lets look at the top view comparison of Canon G7 X MII and Olympus E-M1.
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 (178g ) than the Olympus E-M1 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-M1, the total kit will weigh much higher.
Weather Sealing
Thanks to the weather-sealed body of the E-M1, 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.
