Unprecedented Image Quality
Image quality is superb throughout the zoom range at all focusing distances. Two aspherical elements, one an XA (extreme aspherical) type, ensure high resolution throughout the image area. Two ED (extra-low dispersion) glass elements, two Super ED glass elements and one ED aspherical element minimize chromatic aberration, while Sony’s Nano AR Coating II subdues flare and ghosting. High-performance 1.4x and 2x teleconverters3 are available.
Exquisite G Master Bokeh
Beautiful G Master bokeh is achieved through advanced optical design, an F2.8 aperture and a new 11-blade aperture unit. An XA element manufactured to 0.01-micron surface precision suppresses onion ring bokeh and the new aperture unit helps to deliver natural circular bokeh. Close-up bokeh is superb too, with a minimum focusing distance of just 1.32 ft (0.4 m) at 70 mm and 2.69 ft (0.82 m) at 200 mm.
Fast, Precise AF Supports Creative Shooting
Four of Sony’s original XD (extreme dynamic) Linear Motors deliver high thrust efficiency that boosts AF speed by up to 4x compared to the previous model. When tracking an approaching short-distance runner, for example, tracking while zooming is improved by approx. 30% compared to the previous model, greatly increasing chances of getting the shot.
Professional Movie Capability
The latest lens technology reduces focus breathing, focus shift when zooming and axis shift when zooming. XD Linear Motors and a new aperture drive unit contribute to quiet operation. This lens even has independent control rings for focus, zoom and iris, with a click on/off switch for the aperture ring. Sony’s Linear Response MF feature ensures responsive, direct manual focus control.
