Description
Complementing the optical design, a multi-focus system, which employs two stepping motors, helps to realize impressively fast, accurate, and quiet focus performance, along with full-time manual focus override, to suit both stills and video needs. Vibration Reduction further complements making sharp images by reducing the appearance of camera shake when shooting handheld. The lens also has a unique physical design, which incorporates a top OLED information panel that can be used to quickly confirm aperture and focus settings, and an assignable L.Fn button permits making exposure and settings adjustments via the lens. Additionally, a programmable control ring can be set for intuitive adjustment over a variety of camera and exposure settings.
