There are screw holes in the shutter of SLR cameras.

The hole at the bottom of the camera is a threaded hole for connecting the tripod. The screw hole at the bottom of the SLR camera is called 1/4 screw. The diameter of this hole is an international standard, and all tripods and general photographic accessories use this screw joint. In addition to connecting a tripod, it can also be installed on a handheld stable pan-tilt bracket. Although it is a small hole, it has a great effect. If the screw on the tripod head is bigger than him, add another 3/8 screw.
