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 Pentax K-70 and Canon G7 X side-by-side from the front, back and top in their relative dimensions. Pentax K-70 has external dimensions of 126 x 93 x 74 mm (4.94 x 3.66 x 2.91″) and weighs 688 g (1.52 lb / 24.27 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 Pentax K-70 and the Canon G7 X. Canon G7 X is clearly the smaller of the two cameras. Its body is 23mm narrower, 33mm shorter and 34mm thinner than Pentax K-70. As you can tell, actually this is not a fair size comparison since Canon G7 X has a built-in lens but Pentax K-70 doesn't. Once you put a lens on K-70, its thickness will increase significantly.
Here is the back view size comparison of the Pentax K-70 and Canon G7 X.
Now lets look at the top view comparison of Pentax K-70 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 (384g ) than the Pentax K-70 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 K-70, the total kit will weigh much higher.
Weather Sealing
With its weather-sealed body, we believe that the K-70 has a big advantage over the G7 X which doesn't provide any kind of environmental sealing.
LCD Screen Size and Features
Pentax K-70 and Canon G7 X's LCD screens have the same diagonal size of 3.00 inches.
Canon G7 X features a
Tilting-only screen which is mostly only good for shooting from waist or over-the-head levels. On the other hand, Pentax K-70 sports a
Fully Articulated screen which is more flexible and useful, especially for taking selfies and video.
