The ARRI Ultra Prime 20mm T1.9 Lens (PL)

Ultra Prime lenses come with large, easy to read calibrated scales, uniform diameters and position of focus and aperture drive rings, and uniform position of exit pupil. Ultra Prime lenses are particularly robust and easy to service. The optical performance is superb, even wide open. Floating elements keep the optical performanc up all the way to the close-focusing limit. Distortion is well controlled and so is breathing, especially with the wider angle lenses, where it counts most.
