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 G9 X and Olympus E-PL8 side-by-side from the front, back and top in their relative dimensions. Canon G9 X has external dimensions of 98 x 58 x 31 mm (3.86 x 2.28 x 1.21″) and weighs 209 g (0.46 lb / 7.37 oz) (including batteries). Olympus E-PL8 has external dimensions of 115 x 67 x 38 mm (4.53 x 2.64 x 1.5″) and weighs 357 g (0.79 lb / 12.59 oz) (including batteries).
Below you can see the front-view size comparison of the Canon G9 X and the Olympus E-PL8. Canon G9 X is clearly the smaller of the two cameras. Its body is 17mm narrower, 9mm shorter and 7mm thinner than Olympus E-PL8. As you can tell, actually this is not a fair size comparison since Canon G9 X has a built-in lens but Olympus E-PL8 doesn't. Once you put a lens on E-PL8, its thickness will increase significantly.
Here is the back view size comparison of the Canon G9 X and Olympus E-PL8.
Now lets look at the top view comparison of Canon G9 X and Olympus E-PL8.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Canon G9 X is significantly lighter (148g ) than the Olympus E-PL8 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-PL8, the total kit will weigh much higher.
Weather Sealing
Unfortunately neither the Canon PowerShot G9 X nor Olympus PEN E-PL8 provides any type of weather sealing in their bodies, so you have to give extra care especially when you are shooting outdoors.

LCD Screen Size and Features
Canon G9 X and Olympus E-PL8's LCD screens have the same diagonal size of 3.00 inches.
On the other hand, Olympus E-PL8 features a
Tilting screen where you can change the angle of the screen to make it easier to shoot from waist or over-the-head levels whereas the Canon G9 X has a fixed type screen which provides less flexibility in shooting positions compared to E-PL8.
