Check out the latest in autofocus technology. Fast autofocus performance relies on not only the camera’s ability to detect and track a subject, but also the lens’s ability to keep up. With the new Sony EF135mm f1.8GM, it has four direct-drive motors in two groups that move the glass elements so that they “meet in the middle”.

Additionally, because they are direct drive and do not turn like a screw, the lens can land on the sweet spot much faster.
