Three years ago, the OM-D E-M1 and Lumix GH4 set new standards, not only for the Micro Four Thirds segment but for the mirrorless market as well. They introduced a number of innovations that had never before been seen on a consumer product, but even more importantly, they proved to the masses that a compact system camera had the potential to be a professional tool. The OM-D E-M1 mark II and Lumix GH5 are the culmination of that potential.
