What is USM Camera Lens?
A USM (Ultrasonic Motor) camera lens is a type of autofocus lens that uses ultrasonic vibrations to move the lens elements quickly and quietly, resulting in fast and precise focusing.
The technology behind USM lenses allows for smooth and silent autofocus operation, making them particularly useful for capturing still images and video in quiet environments. They are commonly used in Canon EOS cameras and can be found in a variety of focal lengths and apertures. USM lenses also tend to be durable and long-lasting, making them a popular choice for professional photographers and videographers who require reliable equipment. Overall, USM lenses are a high-quality autofocus option that can help to ensure that your images and video are sharp and in focus.
