Let’s face it…
Canon has a long history of innovation and truly offers a wide range of gear for every type of shooting.
Their first lens with an in-built focusing motor was introduced back in 1987 and since then, they have continued to innovate by introducing three types of motors for modern photography:
- the STM (Stepper Motor),
- USM (UltraSonic Motor), or,
- more conventional DC type motor.
Now, what does STM and USM stand for? What is the difference between STM and USM lens? How does each type work?
It is important that photographers are mindful about which glass suits their needs best; whether it be faster focus acquisition on fast moving subjects, silence during shooting or just easier manual control over their photos.
