In this video, I will explain the differences between: ONE SHOT, AI FOCUS & AI SERVO and when to use them. If you manually focus using your lens, these settings are not available.
Most, if not all digital cameras have this feature. Changing the settings on your DSLR will allow you to take photos of moving objects such as: animals, flowers, cars, aeroplanes etc... Changing the settings to AI FOCUS / AI SERVO allows to sharper images during action shots.
