The diaphragm (iris) is ideal for pistol or rifle shooters who use open sights. Rotating the diaphragm allows us to adjust the focus (depth of field), which improves our ability to see the target in the distance, without losing sharpness in the image of the weapon's sights. It is placed on the lens holder from behind to avoid annoying reflections on the lens. It is valid for right or left-handed shooters.
