That's a beast, the 5D Mk IV! I use mine for more than a year and it still impresses me. The blazingly fast and secure AF, the details — when I shot Crisul Pietros it focussed through an ND1000 filter in Live View. I love it! It brings images almost (almost! - surely not exactly) like a 6×4.5 camera.This bird is great, too, I love the composition and the tones.
