I completed the second stage of the great purge.
First round: I acquired the Nikon Z6 with 24-70mm S and FTZ adapter - and traded in the Nikon D5500, D90, 35mm AF-S DX, 16-85mm AF-S, 18-55mm AF-P, Sigma 30mm f/1.4 Art and 18-35mm Art.
Second round (today): I bought the Panasonic GX9 with 12-32mm pancake zoom and 15mm f/1.7 - and traded in the Olympus E-M10, E-PL7, 12mm, 17mm f/1.8, 14-42mm IIR, Panasonic GX80, 12-32mm (refurbished, faulty - so, a give-away), Sigma 30mm f/2.8 Art.
That's two cameras, three lenses and one adapter in, five cameras and ten lenses out.
The third round may or may not happen. I'm considering trading in the Panasonic LX100 and Ricoh GR for a Ricoh GR III - if and only if that camera proves to be a real upgrade to the original GR.
