Dynamic setting of canon 850D beat

If a SLR camera wants to take a clear picture, it should at least pay attention to the following three aspects:

1. Turn on the autofocus function AF on the lens;

2. Choose the appropriate shutter speed. When shooting with a hand-held camera, the shutter speed should not be lower than the maximum focal length of the lens. If a 70-200 lens is used, the shutter speed should not be lower than 1/200. When shooting a moving picture, the shutter speed should be adjusted to11000 or faster, otherwise it is easy to shoot a virtual image.

3. The light is dim, and if you want to take delicate photos, you must use tripod and other auxiliary tools to stabilize the camera.
