"AF" stands for "autofocus" in the context of photographic equipment. Autofocus is a feature in cameras and lenses that automatically adjusts the focus of the lens to ensure that the subject is sharp and clear in the final image.

Autofocus enables photographers to quickly and accurately capture sharp images without the need to manually adjust the focus ring on the lens. This is especially useful in fast-paced situations such as sports photography or wildlife photography where the subjects are moving quickly and constantly changing distance from the camera. Additionally, autofocus allows photographers to focus on composing their shot and capturing the moment without worrying about manually focusing the lens.

There are different types of autofocus systems, including contrast-detection autofocus and phase-detection autofocus, each with their own strengths and weaknesses. Overall, autofocus technology has greatly improved over the years, providing photographers with fast and accurate focusing capabilities that enhance the quality of their images.
