Weight is another important factor especially when deciding on a camera that you want to carry with you all day.
Nikon 1 J4 is significantly lighter (328g ) than the Nikon D5100 which may become a big advantage especially on long walking trips.

Since Nikon D5100 has an APS-C sized sensor and Nikon 1 J4 has a smaller 1" sensor, Nikon 1 J4's lenses for a similar focal length and aperture will generally be lighter and smaller than the Nikon D5100 lenses.
