Frequently Asked Questions

What Does USM Mean on Canon Lenses?

The USM on Canon lenses stands for Ultrasonic Motor system. It is an autofocus motor type that can switch ultrasonic vibration energy to rotational force so that the lens can move. This allows the lens to focus on the subject way faster than a lens that does not have a USM. 

Canon 40mm lens

The feature is the fastest focusing motor that the manufacturer Canon has ever built. It allows you to work on the manual focus without having to turn off the autofocus mode. 

What Makes USM Different From STM on Lenses?

The Ultrasonic Motor or USM is built for professional photographers who are into capturing pictures, while Stepper Motor or STM is geared towards beginners and those who are into videography. 

Even though USM is advertised as a feature with silent autofocus, you can still hear a bit of focusing the sound on the camera’s microphone when you shoot a video. 

USM is ideal for capturing pictures of live subjects, but it is not ideal for videography, especially if you want to make sure that there is no sound included in your video. 

As for STM, it produces absolutely no sound at all because it was created solely for videography. Even though the focus speed of STM Canon lenses is lower than the focus speed of lenses with USM, it is great for filming videos because it is silent. 

How Are Special Glass Elements Built?

Special glass elements are built by merging two types of glass elements: crown and flint. Both of them are made into one glass that is known as achromatic doublet. 

The crown and flint glasses are needed because they serve as a backup in case one has more characteristics than the other. The doublet is then attached to the lens, creating a special glass. 


The best lens for Canon T7I can help you take incredible images, and it can assist you in pursuing the type of photography that you want to do. 

Knowing the kind of outcome that you want and the features that you need to achieve this can narrow down your search for a lens for your DSLR camera.
