While the drastic size reduction grabs the design and engineering spotlight, a number of customizable controls are also effectively distributed about the lens for both ergonomics and efficiency:
- The lens' center of gravity has been shifted toward the rear of the lens and nearer to camera body, benefitting quick stops and accelerations during handheld panning and allowing for the tracking and acquisition of fast-moving subjects.
- Two programmable function buttons, a control ring, a Memory Set button, and a limiter switch put precision control at your fingertips, with the tactile details that allow for quick adjustments without looking.
- The front grip encourages a stable, comfortable shooting posture in any configuration, while the tripod collar smoothly rotates for shooting in any orientation.
- The lens' advanced weather sealing is rated to keep dust, dirt, and moisture out of moving parts for safe use in the elements, while a Kensington Security Slot keeps your lens safe from theft with the use of optional pro-grade cable locks.
