Thread: Focusing Speed

  1. #1

    Default Focusing Speed

    May I know whether the focusing speed is affected by the camera body ? Will the focusing speed increase if a high-end body is used compare to a normal body.

    AF speed, assuming from the moment u half press the shutter to the shot being taken, is affected by the camera body and the lens u using.

    Speed is determined by body (recognizing image pattern, calculating necessary focus movements of the lens, sending command to lens) and by lens (executing the move) and also by the available light (dim light can cause 'focus hunting' - last resort of AF unit to find focused position of the lens).

    You can make use of zone focusing or hyperfocusing for even faster focusing than depending on AF or some high end equipment.

    Focusing speed can be affected by:

    1. Poor subject and background contrast

    2. Reflective surface

    3. Low light

    4. Subject is behind a piece of glass

    5. Subject is fast moving

    Yes, in a nutshell, the camera can affect the focusing speed.

    Yes, there a some difference between the bodies. Whether the difference is sufficient to make a difference, varies from person to person. See measurement results in links below.
