The Panasonic Lumix S5 and the Sony Alpha a7 IV sit at similar price points in the full-frame mirrorless category, each appealing to hybrid shooters who value stills and video capability. Public specifications show the Lumix S5 at a lighter body weight of 4.47 pounds against the Alpha a7 IV’s 19.6 pounds, while the Sony model carries a lower starting price of $1,399 compared with the Panasonic’s $1,799.
