I fully understood why Nikon and now, supposedly, Canon, would announced Full-Frame mirrorless cameras. Nikon & Canon are leaders in Full-Frame DSLR cameras and have tons of Full-Frame lenses for their DSLR. For them it was the transitioning from DSLR to mirrorless SOMETHING that I knew was inevitable 4-years ago when I decided that I was going mirrorless from the start.
Panasonic makes good cameras and I loved the Panasonic FZ1000 I owned a couple years ago. It took lovely pictures. But, Panasonic doesn’t even have APS-C lenses.
This makes NO sense to I. But, the rumored Canon EOS R sure does.
