It is used in high-performance cameras that require high responsiveness, taking advantage of its excellent mobility.
Even with fast-moving subjects, the high responsiveness allows you to shoot accurately in sync with the photographer's timing.
Because it is cogging-less, it can perform excellently in environments that require high precision in adjusting the amount of light.
In the field of optics, where miniaturization is advancing, smaller sizes allow for greater design freedom.
It is used to adjust the amount of light passing through the lens.
