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 180mm has a minimum close focus of 8.6". 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 180mm 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. While most of the Ultra Primes share a 95mm front barrel diameter, the telephoto 180mm has a 114mm front.
