MIRRORLESS WARS II: Canon vs Nikon, Sony, Fuji, Panasonic!

Tony and Chelsea write:

The first round of the mirrorless wars are over – Canon released the EOS R, Nikon released the Z7 (and announced the Z6), Panasonic announced the S1 and S1R, and Fuji launched the X-T3. We were there at the events as the camera companies battled to win back the full-frame market from Sony. We think some of the camera companies did a great job, while others made some serious mistakes.
