Weight is another important factor especially when deciding on a camera that you want to carry with you all day. Olympus E-M10 IV is significantly lighter (216g ) than the Sony A580 which may become a big advantage especially on long walking trips.

Since Sony A580 has an APS-C sized sensor and Olympus E-M10 IV has a smaller Four Thirds sensor, Olympus E-M10 IV's lenses for a similar focal length and aperture will generally be lighter and smaller than the Sony A580 lenses.
