“[With fixed focus], you don’t need to worry about focusing, you just capture images instantaneously,” said Juha Alakarhu, director of imaging technology development at Microsoft. “In autofocus, there is a short time that the camera needs to find the perfect focus.” In fixed-focus cameras, the lens can’t be adjusted.
Similarly, What does autofocus mean on a webcam? A camera’s autofocus system intelligently adjusts the camera lens to obtain focus on the subject, and can mean the difference between a sharp photo and a missed opportunity.
