What Does Is Mean In Canon Lenses – The difference between an ultrasonic motor (USM) and a stepper motor (STM) comes down to what you use them for. They may share common features such as having an autofocus motor, but they use different autofocus systems.

Canon was the first company to introduce a focus motor inside the lens, which is now standard.

In short, Canon has developed three types of motors for its lenses: STM, USM and traditional DC motors.

The term “USM” on Canon lenses refers to the autofocus motor system used by the lens. USM stands for Ultrasonic Motor and it works by using ultrasonic vibrations converted into rotary motion to move the focus ring. USM lenses have faster autofocus than STM lenses, but are less noisy.

USM stands for Ultra Sonic Motor. Most Canon lenses have this type of motor, and USM lenses are considered the standard for professional photography. They are a huge improvement over DC motors and are quieter and faster.

USM lenses focus faster than conventional lenses, and jumping from one point to another is a piece of cake. With these lenses, you can go from autofocus to manual focus in an instant.

But that’s just scratching the surface. There are three types of USM lenses that you should know about: Ring USM, Mirco USM and lastly Nano USM.

The Only Five Lenses You Need To Own

The former is the most popular choice, but the Nano USM has caught the attention of many professional photographers over the past couple of years.

Ring type USM is a two-ring system. One of them is connected to the focus system/AF group and the other to the barrel. One of them vibrates at an ultrasonic frequency, while the other moves in a rotational fashion. The Ring USM has a full-time manual focus (FTM) feature that lets you easily switch from auto to manual focus.

The Micro USM has a similar sonic vibration motor that is not directly connected to the focus system. It has the same gears as a DC motor, which means it’s also noisy. Designed like gears, these motors are designed to create an efficient focusing system that is not limited by the size of the lens barrel. The Micro USM lens does not have full-time manual focus.

Canon changed the name of the game when they created the Nano USM. It features a new type of mechanism that combines the speed of a USM ring with the quiet focus of a lead screw type STM lens. The motor ring is similar to the USM, but the motion is linear rather than rotary. However, as with the STM motor, focusing must be done by wire (the manual focus ring is not connected to the lens’s focus system). The result is good image quality when shooting stills, fast AF response and smooth focusing when shooting video.

The main advantage of using the Canon USM (UltraSonic Motor) lens is that it provides faster focus than the Canon STM autofocus system. This improved autofocus speed makes Canon USM lenses ideal for photographers, allowing them to quickly switch focus between subjects.

The main advantage of the Ring USM lens is that it focuses in the blink of an eye; Nailing focus is no problem with this lens, making it perfect for all types of photographers, even those who like a lot of action. The downside is that it sounds nice. Also, tight lenses are a videographer’s worst nightmare. But compared to DC motors, the Ring USM lens is very quiet.

Compared to the Micro USM, it allows you to turn off autofocus when switching to manual focus, and there is full-time manual focus (FTM).

Micro USM lenses are very light compared to other USM lenses. Not to mention they are cheap.

On the other hand, the Canon Nano USM is the best deal you can get. Canon designed this system with photographers and videographers in mind. In terms of noise, it approaches the level of STM lenses; It is as fast as Ring USM. So the best of both worlds. Sensitivity and speed make this sharp lens the whole package. Now that’s pretty cool. And they say there is no such thing as a perfect lens.

The term “STM” on Canon lenses refers to the autofocus system used by the lens. STM stands for “stepper motor” and is a focusing system that uses a geared motor to rotate the focus ring. Canon STM lenses have very quiet autofocus, which is great for video, but they take longer to focus than USM lenses.

The STM incorporates stepper motor technology, where power comes from the camera body rather than the lens. The Canon STM system was designed specifically for video shooting. Canon has designed a system with smooth and quiet focus. Focus is smooth, but quite slow compared to USM.

Although it is not clear how this lens works, Canon has installed a focus motor that eliminates noise during shooting. The focus system is rock-quiet, and as any expert will tell you, minimal noise during recording is no mean feat.

Fast Lens: What Is It, And Why Does It Matter?

A stepper motor is an electric motor that rotates in steps. They are driven by a current pulse with a lead screw connected to the AF group. A step is a fixed position, 1/4 clockwise, 1/8 of a turn, etc.; After the rotation is complete, the motor stops.

The downside is that Canon STM lenses don’t have full-time manual focus. When autofocus is enabled, you lose the option to manually adjust the focus ring.

Ring A ring or gear system forms the focus system in a USM lens. The gear movement makes this lens noisier than some others. STM lenses do not have this problem.

STM lenses are the best choice for video recording because they don’t pick up camera focus noise. The audio part of the video is the most important part, so shortening it is a mistake and you will regret it later.

What Do The Numbers On Your Camera Lens Mean?

The focus system is generally smoother and quieter during shooting. STM ensures smooth motion during recording. The STM lens is a content creator/vlogger’s dream because it’s designed for video.

When using the STM lens, the focus is fast enough, which is always convenient for photography. But it’s a bit slower than the Ring or Nano USM lenses.

These lenses are very cheap. If you love video but still want to take the occasional photo, this is a budget-friendly option that shouldn’t be overlooked.

When comparing Canon STM vs. USM lenses, the best choice depends on what you’re shooting. Canon STM lenses are more suitable for video shooters due to their silent autofocus system. At the same time, the Canon USM lens is very fast in finding focus, but a little noisy. The USM system is ideal for photographers because of its high noise level.

The Holy Trinity Of Canon Rf Lenses

There is no correct answer to this question. In general, there is no “better” lens because STM and USM lenses are not designed for the same purpose, they are better for different things.

Photographically, there isn’t much difference between the two options, so if that’s what you want, go for the cheaper option.

For video capture, the STM system benefits from noise reduction. USM lenses can be used for video, but you’ll notice lens noise as your camera moves between different focus points.

The important thing is that you know how to get the best out of your lens. It depends on your preference and what you will be using the lens for.

If you don’t like shouting in your videos, be careful when choosing – older versions of USM lenses are not good enough. Audio and smooth focus are some of the most important aspects of video capture. If you mostly want to shoot video, look no further than the STM or Nano USM lenses. STM lenses are great for photography, but not great for photography.

If you’re shooting a lot of action or wildlife, these lenses are a reliable companion. A quiet lens is essential. There’s nothing more annoying than missing a perfect shot because you spooked an animal a few feet away.

Ring USM lenses are used as the gold standard for focusing speed when taking photos. This is before the Nano USM. However, you will have to pay a little extra for this bonus. The Ring USM lens is a bit quieter, but not as quiet as the STM lens. The latter makes focusing very smooth during shooting.
