The Lightweight Zoom LWZ-1 is the only compact zoom that combines outstanding optical image quality – inherited from the Master Primes – with smooth mechanics and light weight. 4.4 lbs (2 kg) of radical spherical and aspherical lens elements, exotic glass materials and the T* XP anti-reflection coating ensure a sharp, high resolution image that covers the entire Super 35 frame and perfectly matches the other ARRI/Zeiss lenses.
