Size and weight is a big decision factor when you are trying to find the ideal camera for your needs.
In this section, We are going to illustrate Pentax K-70 and Canon 750D 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 750D 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 Pentax K-70 and Canon 750D. Pentax K-70 is clearly the smaller of the two cameras. Its body is 6mm narrower, 8mm shorter and 4mm thinner than Canon 750D.
Here is the back view size comparison of Pentax K-70 and Canon 750D.
Now lets look at the top view comparison of Pentax K-70 and Canon 750D.
Weight is another important factor especially when deciding on a camera that you want to carry with you all day.
Canon 750D 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 have to also take into account the lenses that you will be using with these bodies. Since both Pentax K-70 and Canon 750D have the same APS-C sized sensor, their lenses for a similar focal length and aperture will be similar in size and weight.
With its weather sealed body, we believe that K-70 has a big advantage over 750D which doesn't provide any kind of environmental sealing.
