The Arri Macro lens set stands out for its minimum focusing distance ideal for recording actions or objects located near the camera. The minimum focus distance of the game is 0.15m and belongs to the 16mm T2.1. With the exception of 100mm T 2.8 the game has the opening of T2.1.
They also stand out for the system called “Automatic Iris Control”. This system consists of an internal mechanism that, in combination with the iris and focus helicoids, maintains the aperture of the diaphragm during the course of the focus ring. This occurs in white diaphragms.
However, there is no automatic iris correction when a blue diaphragm is used. Focusing from infinity to a macro position at maximum aperture results in the diaphragm ring automatically positioning itself in the correct diaphragm. Because of this, Arri warns that systems that block the diaphragm ring (Wireless focus controls) should not be used.
