1: Use a tripod to stabilize the camera. If there is cable release, it is best to use cable release.
2. Set the camera to Av, and select the aperture (such as F8) according to the required depth of field and shooting distance; Set the focus switch according to the shooting distance. When the shooting distance is 0.3m-0.5m, the switch is set at the position of 0.3m-0.5m; when the shooting distance is greater than 0.5m, the switch is set at the position of 0.5m- infinity. The switch can also be set to the full position according to the specific situation.
3. Select manual or automatic focusing as required. When using manual focusing, turn the AF/MF switch on the reflector to MF (the new Budweiser can always focus manually, and the autofocus mode is set to single autofocus. After pressing the shutter button of autofocus, you can manually turn the focus ring to focus manually).
