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 Nikon D5300 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). Nikon D5300 has external dimensions of 125 x 98 x 76 mm (4.92 x 3.86 x 2.99″) and weighs 480 g (1.06 lb / 16.93 oz) (including batteries).
Below you can see the front view size comparison of Pentax K-70 and Nikon D5300. Pentax K-70 is 5mm shorter and 2mm thinner than Nikon D5300 but it is also 1mm wider.
Here is the back view size comparison of Pentax K-70 and Nikon D5300.
Now lets look at the top view comparison of Pentax K-70 and Nikon D5300.
Weight is another important factor especially when deciding on a camera that you want to carry with you all day.
Nikon D5300 is significantly lighter (208g ) 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 Nikon D5300 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 D5300 which doesn't provide any kind of environmental sealing.
