Details
The iris shutter is ideal for pistol or rifle shooters, who shoot with open adjustment.
This replaces the diopter and improves the focus (depth of field).
It is mounted on the back of the lens-holder to avoid disturbing reflexes in the lens.
It can be used for right or left aiming shooters. Iris shutters are available for big and small lensholders.
Tip: Before trying to achieve better focus with the iris shutter you should ensure you have the right corrective lens.
