Weight is another important factor especially when deciding on a camera that you want to carry with you all day.
Nikon D3500 is significantly lighter (323g ) 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 D3500 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 K-70 has a big advantage over D3500 which doesn't provide any kind of environmental sealing.
LCD Screen Size and Features
Pentax K-70 and Nikon D3500's LCD screens has the same diagonal size of 3".
On the other hand, Pentax K-70 sports a
Fully Articulated screen which you can change the angle and position of the screen almost freely, making it possible to shoot from waist or over the head levels, and especially very useful for shooting selfies and video. Nikon D3500's LCD screen is a fixed type which provides almost no flexibility in shooting positions compared to K-70.
