Methods and Purpose of Lens Slot Focal Length Adjustment:
The min distance between lens and eyes on the slot is 45mm while the max distance is 65mm. When lens becomes closer to eyes, you may view larger visual range, and vice versa. For example, the focal length of lens is 333mm when using 1.5X lens. If the distance between lens and viewed object is less than 333mm, the focusing component should move in positive direction. And if the distance between lens and object is more than 333mm, the focusing component should move in negative direction.
