The History of Autofocus: From Rangefinders to AI Subject Recognition
Our take
Autofocus represents a remarkable evolution in photography, transforming the way images are captured and experienced. Emerging from the era of rangefinders, this technology has seamlessly integrated into modern cameras, often going unnoticed when functioning flawlessly. With a simple half-press of the shutter, a photographer can effortlessly lock onto a subject—be it a fleeting bird, a moving car, or a familiar face—allowing creativity to flourish.
Autofocus is one of the great invisible revolutions in photography. When it works well, it disappears. A photographer raises the camera, half-presses the shutter, sees a box snap to an eye, a bird, a car, or a face, and the lens silently moves to the right position.
