If you notice your Canon digital SLR camera lens has the letters USM written on the side, it means the lens has a small motor built into the body. Hence, USM is short for Ultra Sonic Motor. What this means is that your lens will autofocus faster than standard models.
Similarly, What does USM stand for in Cameras? USM stands for Ultrasonic motor. It’s a type of motor used in Canon EOS lenses. This is the motor which drives the autofocusing. Non-USM lenses often use an arc form drive (AFD) motor. This is good, but the USM is faster and quieter.
Is II vs is STM? STM is generally considered better if you do a lot of video recording. The II is the second version of the particular lens. If everything else is the same but the II (some have III and if I recall there may be a few with a IV) it means it is a later model of that lens. STM is a type of focus motor.
Beside above, WHAT is STM focusing? When you see a Canon lens with STM in the name, it means that it features Canon’s Stepper Motor technology. Canon introduced this motor design to be a quieter and smoother focus system that allows for near-silent focusing during video recording.
What are EF lenses?
EF lenses were introduced in 1987 for Canon SLR cameras, and EF stands for “Electro-Focus” because it has a built-in motor in the lens for automatic focusing. The camera and the lens use electrical metal contacts to communicate as opposed to levers and plungers.
What IS Canon Nano USM? Nano USM lenses use a motor system that combines the benefits of a ring ultrasonic motor (USM) with a lead-screw type STM (stepping motor). USM delivers high speed focusing for photo shooting, while STM allows for smooth and quiet focusing for video recording.
What IS the L in Canon lenses? Canon sells regular and L-series lenses (the “L” stands for luxury). While the lenses may have similar specs, you can usually except L-series lenses to have better optics, build quality, and autofocus control, and a few more features.
What IS a mirror lens? What Is a Mirror Lens? In a nutshell, a mirror lens is a compact telescope. Conventional, or refractive, camera lenses use formulated clusters of glass elements to gather light and transmit the focused image to the camera sensor (or film surface).
IS STM a USM?
USM stands for Ultrasonic Motor, while STM stands for Stepper Motor. Both are autofocus motors built into different lenses you’ll find in Canon’s lineup.
WHAT IS STM on Canon lens? STM stands for Stepper Motor.
In June 2012 Canon introduced a new lens motor design to address the issue of lens noise when shooting movies with an EOS DSLR camera. Called a Stepper Motor, it converts digital pulses into mechanical rotation.
How do I know if my Canon lens IS STM?

IS STM lens good for photography?
Smooth focus: other focus systems can be jerky, but STM lenses focus smoothly and with precision — perfect for video. A still photographer won’t care about this, but smooth focus can make all the difference when it comes to a video.

What is Nano USM? Nano USM (ultrasonic motor) is Canon’s latest generation of lens motors, combining the speed of USM motors with the silent action of their STM motors.

Is EF or EF-S better? So if you’re a landscape or architectural shooter, or you just want an ultra-wide angle perspective, it’s better to use a full-frame camera with EF lenses. Plus, EF lenses are much more expensive than EF-S lenses. If you’re on a budget, you’ll appreciate the money you can save by purchasing EF lenses instead.
What is the difference between Canon EF and EF-S?
The primary difference between Canon EF and EF-S lenses is that EF lenses are designed to work with both full-frame and APS-C DSLR bodies, while the EF-S lens line is designed to work only with APS-C bodies.
IS USM Nano vs STM? Ring USM lenses are best for still photography, but the Nano USM mechanism is excellent for both video and still photography. The Nano USM lens is also significantly quicker than the STM when it comes to tracking moving subjects, making it a better focus hunter.
What is Nano lenses?
With this in mind, Nano Crystal Coat that consists of nanometer-sized* particles is applied to the surface of a lens. This reduces the difference in refractive index between the glass and air by creating a structure that has spaces between one particle and another.
