I would a full frame SL mount camera with a Sigma Foveon Sensor. I would also buy Pana-Leica lenses with SL mount.
I think this is a very exciting partnership.
Panasonic is the one company in the world with sufficient prowess in electronics to beat Sony.

These days I shoot mostly with Sony A7Riii, Sigma Quattro SD H, Panasonic G9, Panasonic GH-5.
