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 Olympus E-M5 and Canon G7 X side-by-side from the front, back and top in their relative dimensions. Olympus E-M5 has external dimensions of 122 x 89 x 43 mm (4.8 x 3.5 x 1.69″) and weighs 425 g (0.94 lb / 14.99 oz) (including batteries). Canon G7 X has external dimensions of 103 x 60 x 40 mm (4.06 x 2.36 x 1.57″) and weighs 304 g (0.67 lb / 10.72 oz) (including batteries).
Below you can see the front-view size comparison of the Olympus E-M5 and the Canon G7 X. Canon G7 X is clearly the smaller of the two cameras. Its body is 19mm narrower, 29mm shorter and 3mm thinner than Olympus E-M5. As you can tell, actually this is not a fair size comparison since Canon G7 X has a built-in lens but Olympus E-M5 doesn't. Once you put a lens on E-M5, its thickness will increase significantly.
Here is the back view size comparison of the Olympus E-M5 and Canon G7 X.
Now lets look at the top view comparison of Olympus E-M5 and Canon G7 X.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Canon G7 X is significantly lighter (121g ) than the Olympus E-M5 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, the total kit will weigh much higher.
Weather Sealing
With its weather-sealed body, we believe that the E-M5 has a big advantage over the G7 X which doesn't provide any kind of environmental sealing.
LCD Screen Size and Features
Olympus E-M5 and Canon G7 X's LCD screens have the same diagonal size of 3.00 inches.
Both cameras feature
Tilting screens where you can change the angle of the screen to make it easier to shoot from waist or over-the-head levels.
