When you are looking to purchase a lens for your camera, there are many options to choose from. You may be wondering what the difference is between USM and IS lenses. In this blog post, we will discuss the differences between these two types of lenses and help you decide which one is best for you.
USM lenses are designed with a built-in ultrasonic motor that provides fast, smooth, and quiet autofocus. They are typically higher quality than IS lenses and tend to be more expensive.
IS lenses feature image stabilization technology that helps prevent blurry images due to camera shake. This technology is helpful for capturing photos in low light or when shooting handheld.
What is USM?
USM is an acronym for the ultrasonic motor. USM lenses use a motor to focus the lens quickly and quietly. USM lenses are found in Canon’s L-series of lenses. USM lenses use a ring USM, which means that the focusing ring does not turn during autofocusing. The main advantages of USM lenses are their speed and accuracy when focusing, as well as the fact that they are nearly silent when in operation. USM lenses are typically more expensive than non-USM lenses, but the extra cost is often worth it for professional photographers who need the extra performance.
What is IS?
- IS stands for image stabilization, and it’s a feature that’s available on some lenses. IS is helpful for reducing blur in photos, and it can be especially useful when shooting in low light or when using a long focal length lens. IS works by using tiny gyroscopes to sense camera movement and then compensating for it with tiny adjustments to the lens elements.
- This helps to keep the sensor in the same position relative to the subject, which can result in sharper images. There are different types of IS systems, and some lenses have multiple IS modes that can be used for different situations.
- IS is a great feature to have, but it’s important to keep in mind that it won’t completely eliminate all camera shake. IS is most effective when used in combination with a tripod or other support system.
Difference between USM and IS
USM and IS lenses are both popular options for photographers, but they serve different purposes. USM lenses are designed for faster autofocusing, while IS lenses are intended to reduce camera shake. USM lenses typically have better image quality, but they are also more expensive. IS lenses, on the other hand, are less expensive but can be less sharp.
When choosing between USM and IS lens, it is important to consider your needs as a photographer. If you need fast autofocus or want the best possible image quality, USM is the way to go. However, if you are on a budget or often find yourself shooting in low-light conditions, IS may be a better option. Whichever you choose, make sure to do your research so that you can get the most out of your investment.
Conclusion
While both lenses offer great features and benefits, there are a few key differences you should be aware of before purchasing. The Canon USM lens is known for its fast and accurate autofocus, while the Image Stabilization lens is perfect for reducing camera shake. If you’re looking for a lens that offers great image quality and reduced blurriness, the IS lens may be the better option for you. However, if speed and accuracy are your top priorities, go with the Canon USM lens.
