ARRI Zeiss Master Zoom 16.5 - 110

Performance with Power

Technological progress in the fields of lens design, optical glass materials, anti-reflection coating, optical metrology, precision machining and surface hardening have enabled the ARRI Rental Group and Carl Zeiss to bring you the Master Zoom 16.5 - 110. A high performance T2.6 zoom lens that provides outstanding optical image quality.

Exclusively available in the UK from ARRI Media, the Master Zoom covers the whole Super 35 frame over the entire zoom range, while displaying very little breathing. This is because sophisticated design and manufacturing techniques have been utilized in the Master Zoom, including the use of exotic glass materials, to ensure the highest optical performance.

An important issue in zoom lens design is the correction of optical aberrations (such as chromatic aberration (colour fringes), and in particular, field curvature) across the whole operating range of the lens; this is considerably harder in a zoom lens than a fixed lens, which needs only to correct the aberrations for one focal length. The Master Zoom forms a high contrast, high-resolution image with almost no chromatic aberration. The novel optical design helps in reducing spherical aberration but more importantly keeps the image geometry free of distortions, so straight lines stay straight, from infinity to close focus.

Another issue with many zoom lenses is that as you zoom in, the picture can get slightly darker - a condition referred to as ‘lens ramping’. The greater the zoom ratio the more difficult this condition is to prevent, but with the Master Zoom there is no lens ramping as its design ensures that the aperture holds effectively while zooming.

The new Zeiss T* XP multi-layer, anti-reflection coating reduces veiling glare and internal reflections, while creating a pleasing colour balance. Compared to conventional coatings, the T* XP coating has better transmission with a more uniform performance across the lens, from the optical centre to the edges. The Master Zoom’s design also provides superior damping of stray light and flare through internal light traps and strategically painted lens rims. The various light traps incorporated into the mechanical design keep unwanted light from bouncing around inside the lens and several types of proprietary black paints with different refractive properties have been used to blacken lens rims for maximum absorbing effect. All of these factors result in higher contrast with deeper, richer blacks, while a round iris opening creates natural looking out-of-focus highlights.

The Master Zoom has been Super Colour Matched to fit perfectly with all other modern ARRI Zeiss lenses, allowing shots to be easily intercut. The design of the focus, zoom and iris scales have also been matched to other ARRI Zeiss lenses for familiar handling and, as with the Master Primes, the focus ring is reversible for easy switching between metre and feet scales. All mechanical parts have been engineered for an extremely smooth feel and the Master Zoom’s unique active temperature compensation ability means that focus and image
quality can be maintained over a wide range of temperatures.

Superior performance and ease of operation is exactly what you expect from ARRI Zeiss lenses, the new Master Zoom lens offers great optical and mechanical performance.
