Moving along the top of the slider, the Nano USM directly drives the main AF power source. The Nano USM is shaped like a computer chip, and has 2 transducers in its center.Ī cross section of the EF-S18-135mm f/3.5-5.6 IS USM, released in 2016 and the first lens to carry the Nano USM. Also very suitable for movie-shooting, its high speed AF is able to handle scenes with subjects that are moving at a fast speed as well as those with unpredictable movements. Its main benefit lies in enabling quiet, smooth AF operation in compactly-sized lenses such as standard zoom lenses. It possesses a speediness and responsiveness that rivals that of the Ring USM, combined with a control that equals that of STM (lead screw-type). Computer chip-shaped (a factor that allows a more compact lens design) with power sources in the form of transducers, it connects directly to the AF actuating mechanism. Thin and compact, this USM, the latest to be developed by Canon, made its debut in 2016 on the EF-S18-135mm f/3.5-5.6mm IS USM. Nano USM-The thin and tiny USM motor that achieves fast and smooth AF

It’s not an exaggeration to describe Nano USM as the most ideal motor for normal-use lenses that are meant to handle both still photography and movie shooting. And in 2016, Canon introduced Nano USM, which not only realizes a high speed AF that rivals that achieved by Ring USM, but also is able to operate quietly and seamlessly. The worlds first mid-telephoto distance macro lens to include shift direction image stabilization, capable of taking life size shots without attachments. In 2002, Canon contributed further to the downsizing of lenses with the development of the Micro USM II, which is about half the size and weight of the Micro USM. Meanwhile, the Micro USM can be employed on many types of lenses because it is low in cost and not subject to restrictions on the lens diameter.

It is especially useful for driving lenses such as large-diameter or super telephoto ones due to its high torque, and it also allows for full-time manual focusing.
The round-shaped Ring USM is simple in structure, and is best suited for use in a circular lens tube. Not only does it consume little power, it has high efficiency, torque and response, enabling high-speed focusing with almost no operating sound emitted. USM drives the lens by transforming ultrasonic vibrations into rotation energy. USM (Ultrasonic Motor) was first put into practical application in the world by Canon.
