Weight is another important factor especially when deciding on a camera that you want to carry with you all day.

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 Nikon D5200 and Pentax K-70 have the same APS-C sized sensor, their lenses for a similar focal length and aperture will be similar in size and weight.
