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 (245g ) than the Sony A68 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 Sony A68 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
Unfortunately neither the Sony SLT-A68 nor Nikon D3500 provides any type of weather sealing in their bodies, so you have to give extra care especially when you are shooting outdoors. If weather sealing is a must-have feature for you, check these sections: Top DSLR Cameras with Weather Sealing
LCD Screen Size and Features
Nikon D3500's 3.00" LCD screen is slightly larger than Sony A68's 2.7 screen.
