Nano AR coating
This lens coating has been designed to accurately transmit light while reducing the negative effects of glare, reflection and ghosting. This creates shots with enhanced contrast, clarity and overall image quality.
Optical SteadyShot image stabilisation
Optical SteadyShot keeps your image stable even when your hands aren’t. By compensating for the minor hand motions that can cause blurring and distortion, Optical SteadyShot ensures brilliant photographic results – even at high zooms.
9-blade circular aperture
The unique 9-blade circular design lets the aperture remain almost perfectly circular even when stopped down by two stops. This makes it possible to achieve smoother, more natural defocusing in your images – including artistic blurring or 'bokeh' – and greater control over the depth of field.
Constant F4 maximum aperture
Shooting at a constant F4 aperture across the entire 70–200mm focal length, you’ll always be able to capture sharp, controlled images. At full zoom, you can lower your ISO setting and increase your shutter speed, so you can capture every second of the action without the worry of noise distortion.
