First, set the shooting mode to M position, then set the A/M selector switch on the lens to M, use manual focusing, and then select the focusing mode in the camera as MF, that is, manual focusing, so as to complete all the settings of manual focusing and carry out real manual focusing.

Manual focusing requires the photographer to know enough about the aperture and shutter, accurately judge what kind of aperture and shutter should be set to make the photo accurately exposed, and require the photographer to change and adjust the aperture and shutter accurately at any time according to the changes of environment and light. For example, it takes 1 1 aperture1125 a second to take a portrait in the sun. Then, when clouds come to block the sun or people move to the shadow to shoot, then the aperture should be adjusted to 8, or the speed should be adjusted to 1/60 seconds to ensure the accuracy of exposure.
