The Olympics is often used by Canon and Nikon as a test bed for new professional cameras. Both had there new mirrorless cameras being tested which is good to see. The high end pro mirrorless Canon’s and Nikon’s will not be for me but will suit a lot of photojournalist and wildlife photographers.
Canon and Nikon are building out well and while still have a way to go to catch Sony range of glass, they have produced some stunning bodies and glass so far. In fact for the cost the Nikon glass has been simply outstanding. Come on Nikon release that f/1.2 35mm and 85mm you have on your drawing boards.
I am feeling the pull of the Nikon Z system and with all my Nikon glass its certainly difficult to justify going to another system.
