Introduction

Canon is a well-known brand in the world of photography. They offer a wide range of lenses, but two of their most popular types of autofocus motors are STM and USM. In this article, we will discuss the differences between these two motors and help you decide which one is better for your photography needs.

What is STM?

STM stands for Stepping Motor. This type of motor is designed to provide smooth and quiet autofocus when shooting videos. STM lenses are also great for photography, especially for capturing still images of stationary objects.

Advantages of STM

The main advantage of STM is its quiet and smooth autofocus, which is ideal for video recording. It also provides accurate and fast autofocus for still images, making it a great choice for beginners and professionals alike.

Disadvantages of STM

One of the main disadvantages of STM is that it’s not as fast as USM when it comes to autofocus. This can be a problem when shooting fast-moving objects or in low light conditions.

What is USM?

USM stands for Ultrasonic Motor. This type of motor is designed to provide fast and accurate autofocus for both still and moving objects. USM is also great for shooting in low light conditions.

Advantages of USM

The main advantage of USM is its fast and accurate autofocus, making it a great choice for sports and wildlife photography. It’s also great for shooting in low light conditions, as it can focus quickly and accurately even in dimly lit environments.

Disadvantages of USM

One of the main disadvantages of USM is that it’s not as quiet as STM, which can be a problem when shooting videos. It’s also more expensive than STM, which may not be ideal for beginners or those on a tight budget.

Conclusion

Both STM and USM have their advantages and disadvantages. If you’re looking for a lens that provides smooth and quiet autofocus for video recording, then STM is the way to go. However, if you need a lens that can focus quickly and accurately on fast-moving objects or in low light conditions, then USM is the better choice.

Ultimately, the decision between STM and USM depends on your photography needs and preferences. We hope that this article has helped you make an informed decision and choose the right autofocus motor for your next Canon lens.
