What are the benefits of manual focus and how to operate manual focus

1. Autofocus often focuses on the object closest to the lens.

When shooting portraits, the focus should be on the pupils of the person, because "the eyes are the windows of the soul", only when the eyes of the bright eyes are photographed, the portrait will be expressive, and the manual focus can just give full play to its strengths, which can avoid the embarrassment of the autofocus to shoot the eyes, but the focus is on the nose. When shooting flowers, it is customary to focus on the stamens of the subject, and manual focus is not afraid of the interference of branches and leaves in front of the lens, which is more active and convenient than autofocus.

2. Manual zoom ring saves camera power.

3. The manual zoom ring can also change the focal length of the camera in a long time, and shoot a dynamic one.

4. When the light is low, the autofocus is hesitant, so I have to use manual focus at this time.

Autofocus is the camera focuses on the ignition area with large contrast between light and dark in the environment, but sometimes in an environment with less contrast, the autofocus will not find the focus, for example, if you focus on a white wall, you often can't automatically find the focus; Another example is that in very dark environments, in the absence of other light sources, the autofocus usually does not find the focus.

Therefore, in the above situation, manual focus shows his advantage, but it requires a high level of technical mastery for the photographer, especially when capturing.

Manual focus is faster and gets it right the first time, it doesn't go over and over like automatic, and it's more accurate in push-pull style.

On the single reflex lens, turn the paddles at the MF and AF (manual, automatic) switches to MF, turn the dial to M mode (manual mode), align the eyesight with your eyes, and manually adjust the lens focus ring until the clarity of the subject you need to align is 100% and press the shutter button, which is a successful manual focus.

Manual focus refers to a method of focusing that is achieved by turning the focus ring of the lens or stepping by pressing the arrow keys of the camera body to achieve clear focus. In the era of digital cameras, manual focus is generally used when the autofocus is wrong, and it is a powerful supplement to the autofocus and is still an indispensable function in the digital age.
