High contrast is achieved by superb control of black reproduction, and a re-design of the lens optics help to reduce ghosting, flare, veiling glare, chromatic distortions and internal reflections.
With its high-grade optical components and precision optomechanical assembly, the lens offers a 45× zoom ratio that can extend to 437mm, and as far as 874mm with the built-in 2x extender. A new and improved built-in image stabilization system features higher frequency vibration suppression and panning operability, making it ideal for shooting in dynamic environmental situations such as within helicopters, boats and motor vehicles.
