| - | Vizy can work with two types of lenses -- M12 and C/CS-mount. M12 is the same type of lens commonly used with action cameras like GoPro. C/CS-mount is often used in industrial/security applications. Being able to use both types of lenses means Vizy can be used with a wide range of off-the-shelf lenses. Since Vizy has an actuated IR-cut filter, it's recommended that you use lenses that do not have IR-cut filtering. Fortunately, these lenses are easier to find. | + | Vizy can work with two types of lenses -- M12 and C/CS-mount. M12 is the same type of lens commonly used with action cameras like GoPro.

| - You can extend the zoom lens' focus range by adjusting the "back focus", that is, the distance between the back of the lens and the image sensor. You can adjust this by loosening the set screw (red arrow below), and rotating the lens such that it rotates within the lens mount. You may need to remove the focus set screw as before. When you are happy with the back focus distance, retighten the set screw to fix the back focus. | - You can extend the zoom lens' focus range by adjusting the "back focus", that is, the distance between the back of the lens and the image sensor.
