What does photography af mean?

1. The AF function of the camera refers to the autofocus function of the camera. Auto focus is auto focus. When using AF autofocus function to take pictures, the camera can automatically focus and track according to different subjects, thus ensuring the correct focal length and clear picture. When using the AF function, the camera can automatically select the focus point to determine the focus position in the picture, and for the moving camera, it can also automatically complete continuous focusing and focus tracking. AF autofocus function is fast and accurate, which can adapt to most situations of different subjects in different occasions.

2. When using AF autofocus function, it should be noted that the necessary parameters should be set according to the specific conditions of different subjects to ensure the success and accuracy of camera autofocus. These commonly used parameters mainly include: single focus and continuous focus, wide focus and standard focus, automatic focus selection and manual focus selection, face recognition focus and so on. Different manufacturers have different names for AF function parameters, but their meanings are similar. These parameters must be set by the photographer before shooting.

3. Although AF has strong focusing ability and high degree of automation, AF is not omnipotent. In some special occasions, AF autofocus will not be able to complete the focusing work, such as dark light occasions or monochrome shooting occasions without contrast. At this time, it is necessary to switch to manual focusing to complete the focusing work.
