What is a dual field lens and what are its advantages?

Dual-field lenses have only two fields of view: a large field and a small field.  The speed is very fast when switching back and forth between the two fields of view, and when the switching is completed, the picture is still clear, which is very advantageous for medium and long-distance observation, and the ability to switch quickly when a target is found.

Can the lens be used freely with the movement?

For this lens, we use a stepper motor. The control mode of the stepper motor is different from that of the DC motor, so not every movement can control the lens. We need to find a movement compatible with the stepper motor, and our company can provide such movement if necessary.
