Beyond the Distance Scale: Why “Close Focus” is an Optical Illusion and How ARRI is Redefining Cinematographic Magnification

Executive Overview In the high-stakes world of professional cinematography, a persistent misunderstanding continues to shape how directors of photography (DPs), camera assistants, and visual effects (VFX) supervisors select and utilize lenses. For decades, the industry has relied on "close focus distance"—the minimum focus distance (MFD) marked on a lens barrel—as a primary metric to determine…
