STM Camera Lens

What is STM Camera Lens?

An STM (Stepping Motor) camera lens is a type of autofocus lens that uses a stepping motor to move the lens elements quickly and quietly, allowing for smooth and precise focusing when capturing still images or recording video.

STM lenses are designed to work especially well with Canon EOS cameras, providing near-silent operation and fast, accurate autofocus for both photos and video. The STM technology also helps to reduce focus "hunting," or back-and-forth movements of the lens during focusing, which can be distracting in video recordings. STM lenses are available in a range of focal lengths and apertures, making them suitable for a variety of photography and videography needs.
