What camera does a sports photographer use?

Sports photographers use Canon's 5D4 SLR camera.

Canon 5D4 adopts Canon full-pixel dual-core CMOSAF focusing system. Each pixel on the sensor can capture light while focusing, which greatly improves the speed of autofocus, reduces the need for the camera to select and capture objects, and quickly finds the correct focus, especially in the field of video shooting.

Canon 5D4 is equipped with about 1.5 million pixel RGB+ infrared photometric sensor. The high-pixel photometric sensor can capture the viewfinder image as an image and detect the colors of objects and faces. Rich subject information is transmitted to the automatic system to improve the accuracy of automatic exposure, automatic white balance and automatic focusing.
