The lens is made of 19 elements in 14 groups, including one large-diameter super ED lens element and two large-diameter ED lens elements to minimize chromatic aberration. High-precision polishing technology, developed for broadcast lenses, has been used to prepare the large-diameter lens elements to achieve outstanding image-resolving performance and creamy bokeh. This element is produced with an accuracy of less than 0.1μm High-speed AF is made possible thanks to the lightweight focus lens group and the use of linear motors.
The lens is lightweight yet robust, thanks to its magnesium alloy construction. The barrel is sealed at 17 places to make the lens resistant to dust, moisture, and low temperatures down to -10 degrees Celsius. The front lens element is coated with fluorine to repel water and dirt, adding extra durability so that the lens can be used outdoors with peace of mind. The matte silver color reduces the risk of the lens overheating under intense summer temperatures. The paintwork is designed to diffuse light which prevents the lens from generating strong light reflections.
