Iris Shutter Knobloch 23 mm

The iris shutter is ideal for pistol or rifle shooters, who shoot with open adjustment. This replaces the dioptre and improves the focus (depth of field).

It is put on the lens holder from behind to avoid disturbing reflexes in the lens. It can be used for right or left aiming shooters. This iris shutter is suitable for 23 mm diameter lens holders.
