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 T6i 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 T6i has external dimensions of 132 x 101 x 78 mm (5.2 x 3.98 x 3.07″) and weighs 555 g (1.22 lb / 19.58 oz) (including batteries).
Below you can see the front-view size comparison of the Pentax K-70 and the Canon T6i. Pentax K-70 is clearly the smaller of the two cameras. Its body is 6mm narrower, 8mm shorter and 4mm thinner than Canon T6i.
Here is the back view size comparison of the Pentax K-70 and Canon T6i.
Now lets look at the top view comparison of Pentax K-70 and Canon T6i.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Canon T6i is significantly lighter (133g ) than the Pentax K-70 which may become a big advantage especially on long walking trips.
Also keep in mind that body weight is not the only deciding factor when comparing two interchangeable camera bodies, you also have to take into account the lenses that you will be using with these bodies. Since both Pentax K-70 and Canon T6i have the same APS-C sized sensor, their lenses for a similar focal length and aperture will be similar in size and weight.
Weather Sealing
With its weather-sealed body, we believe that the K-70 has a big advantage over the T6i which doesn't provide any kind of environmental sealing.
LCD Screen Size and Features
Pentax K-70 and Canon T6i's LCD screens have the same diagonal size of 3.00 inches.
Both cameras feature
Fully Articulating screens where you can change the angle of the screen to make it easier to shoot from waist or over-the-head levels. Fully articulating screens are also useful for taking Selfies and video.
