Hey, let's face it: the new and monstrous Canon EOS 1 Dx Mk III is not so good for street as the Sony A7 Mk IV. Why? Canon has so much mojo and so many die-hard admirers! Stop. Let's face it: nowadays it is very easy to freeze the acrion by using high shutter speed. Most cameras can do it. Many cameras have clean ISO up to 1600 which is enough. With Sony's huge resolving power you can crop your shot heavily and still have enough quality so that your cropped shot be introduced at a photo exhibition or in a book. You may shoot with 35 mm lens but cropping it (while editing), you can get strong "digital zooming" as if you used 85 mm lens and have super clean and detailed image enough for A2 size printing! Sony is much smaller, eye recognition and has 5-axis stabilization too. Good bonuses.
