Canon lens names consist of four primary components: the lens mount, focal length, aperture, and an acronym made up of three letters—usually either “STM” or “USM.” You might be wondering: What do they mean?
In general, the three-letter acronym you find on Canon camera lenses indicates the type of focusing motor on the lens. “STM” stands for Stepper Motor Technology, while “USM” refers to the Ultrasonic Motor. Therefore, a Canon EF 50mm f/1.8 STM lens will mean that it has an Electronic Focus (EF) mount, a focal length of 50mm, a maximum aperture of f/1.8, and Stepping Motor Technology.
STM lenses are typically known for having smoother focus. As a result, they are ideal for filming videos; however, they may also be used to shoot photos. Moreover, STM lenses have the following advantages:
· Quiet focusing
In addition to their smooth focus, STM lenses are also very quiet. They are so quiet, in fact, that the camera will not be able to pick up the focusing sound when recording audio. This means that STM lenses are best for shooting vlogs, commercials, and other video content.
· Relatively fast focus
One advantage of USM and Nano USM lenses is their speed, which makes them ideal for taking photographs. However, this doesn’t mean that STM lenses are slow. They can still be used for photography, especially when you don’t need to shoot fast-moving subjects.
· Affordable price
STM lenses are some of the most budget-friendly options in Canon’s line-up. So, if you’re a beginner photographer or videographer who wants to improve your skills and practise with high-quality gear, STM lenses are the way to go.
