For the very first time in 15 years, I'm considering switching to sony. Canon has done a great effort to loose a loyal client with 8 Canon prime lenses and 3 Canon bodies. I became a film maker thanks to canon 5d mark II. Love the color science. Then Magic Lantern saves Canon to change my camera. Then I was forced to bought a Sony A7s II to get 4k video. Hate the colors, lack of AF, Menu system, battery life, LCD and monitor brightness and sharpness, grip, among many other things. Then canon gave us Canon 5ds with 1080 video, 5d mark IV with 1.7x 4k crop factor and the (new) videoless canon RP, a museum camera than came from the past to the future!
Now my business partner bought a sony a7r iii ( he already has 4 camera bodies and more than 10 canon lenses) and again I hate color, EVF viewfinder and... that's it. Improved battery life, great AF performance with metabones adapters on Canon glass, better Menu, better LCD monitor. 42 megapixels. 4k full frame video. Two SD slots. In camera stabilizer.
I would pay for being on the head of Canon's marketing guys. I just don't understand them. I WANT a Canon camera, but I WILL need to buy a Sony one, agian. It's like if Sony had secretly bought Canon and we still don't realize about it.
I wish I have enough money to get an ARRI camera and let these people behind.
