ARRI Ultra Prime 100mm T1.9 is a PL-mounted prime lens that covers the Super-35 format. The 100mm is a longer entry in the comprehensive array of Ultra Prime focal lengths from 8mm to 180mm. The Ultra Primes provide a compact, lightweight, optically-matched complement to the higher-speed ARRI Master Prime series. Compatible with both HD and film cameras, the Ultra Primes are color matched to each other and to the rest of the ARRI lens spectrum.

The Ultra Primes provide the optimal image quality, vivid colors, and skin tones for which ARRI/Zeiss are known. Each lens in the series features a T* XP lens coating for reduced glare and minimized reflections. The Ultra Prime 100mm has a minimum close focus of 3’3″. The lenses’ fast, maximum aperture of T1.9 enables shallow depth-of-field shots. Minimal focus breathing does not draw attention to focus pulls, preserving the viewer’s cinematic experience.

The Ultra Prime 100mm 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. Its industry-standard 0.8 Mod focus and iris gears interface with manual follow focus units and with wireless lens control motors. All 15 lenses in the Ultra Prime series share common focus and iris gear positions, making for fast lens swaps with no need to reposition lens accessories. Likewise, the 100mm prime shares the 95mm front barrel diameter common to all but the extreme ends of the series of focal lengths, saving time otherwise spent swapping out matte box adapter rings.
