The ARRI Ultra Prime 14mm T1.9 is a PL-mount prime lens that covers the Super-35 format. The Ultra Primes provide a compact, lightweight, optically-matched complement to the higher-speed ARRI Master Prime series. The Ultra Prime 14mm lens barrel is marked in feet and has focus markings on both sides of the barrel, enabling the focus puller to easily work the side of the lens best suited for each setup.
