The use of seven ED glass elements provides the ultimate in rendering characteristics for capture of images exhibiting excellent resolution and high contrast. The additional use of Nano Crystal Coat effectively suppresses ghost and flare for clear images. Adoption of the Silent Wave Motor (SWM) allows for smooth and quiet autofocusing that makes the most of camera autofocus subject tracking systems. The lens also provides superior operation with three focus modes — M, A/M, M/A — for manual focusing or manually fine-tuning focus acquired with autofocus by simply rotating the lens' focus ring. The vibration reduction system (VR II) provides camera shake compensation equivalent to increases in shutter speed by four steps*. Two vibration reduction modes are available. NORMAL mode: The vibration reduction mechanism reduces ordinary camera shake. Panning is also supported.
ACTIVE mode: The vibration reduction mechanism reduces extreme camera shake, such as that which occurs with shooting from a moving vehicle.
