Canon 5D4, Nikon D850 and Sony A7R3 have better photographic quality?

Canon EOS 5D Mark IV adds "4K video recording" and "full pixel dual-core RAW", which is also the first time in the "5D" series. In addition to 4K(30 frames), the recording capability can also support 720P( 120 frames) and 1080P(60 frames). The full-pixel dual-core CMOS AF introduced from 80D will also make video shooting more convenient, and the 3.2-inch 162000 touch screen also supports touch focusing. In Canon DPP(Digital Photo Professional) software, full-pixel dual-core RAW can perform fine-tuning of images, defocusing and ghosting reduction. In short, the adjustable range of RAW photos is wider.

As for other specifications, Canon EOS 5D Mark IV is equipped with Quan Huafu CMOS with an effective pixel of 30.4 million pixels (still independently produced by Canon), the image processor is upgraded to DIGIC 6+, and the native ISO is ISO 100 ~ 32000 (higher sensitivity than the previous one), which can be extended to 50 ~ 102400, and the shutter is/kloc-. Although the number of pixels has increased a lot, the continuous shooting speed has increased to 7fps. In autofocus, the full-pixel dual-core AF is adopted, and the focus is still 6 1 (including 4 1 cross focus), which is the same as the previous work, but the 6 1 point is upgraded to F8 aperture support, and the minimum phase focus supports -3EV. The touchable back screen mentioned above also supports touch focusing. In terms of connection, 5D Mark IV supports Wifi and NFC to connect mobile phones for sharing, and the body is also equipped with a GPS module. Canon EOS 5D Mark IV body is divided into dual CF and dual SD card slot versions.
