|An F2.8 telephoto zoom like no other
The most advanced technology available has been applied in the G Master series, further refining acclaimed Sony G Lens performance. This model combines refined G Lens bokeh with new levels of resolution in an outstanding constant F2.8 telephoto zoom that offers unsurpassed rendering, blazing AF, and extraordinary image stabilization performance.
|Extraordinary detail and bokeh in one lens
Specifically designed to resolve spatial frequencies with excellent contrast, this lens includes three aspherical elements, including one double-sided and one newly developed XA (extreme aspherical) element with 0.01 micron surface precision, to effectively control aberration for astonishing resolution plus glorious bokeh.
|Natural images without spurious colour
Chromatic aberration that can be a problem in telephoto lenses is thoroughly suppressed by the use of four ED (Extra-low-Dispersion) glass elements and two Super ED glass elements. Colour bleeding is banished so the subject can be captured with maximum sharpness.
|Further refinements for spot-on movie AF
The focusing system’s double linear motor takes on the vital role of providing “wobbling” actuation for the AF contrast detection system when shooting video. An optical design that effectively minimizes focus breathing plus quiet mechanical operation further adds to focusing performance that is ideal for movies as well as stills.
|Fast AF optimized for stills and video
Two heavy focus groups are rapidly and precisely positioned by separate actuators: a powerful RDSSM (Ring Drive Super Sonic wave Motor) actuator for the front group, and a double linear motor actuator for the rear group. Improved positioning precision works with real-time feedback from multiple position sensors to allow the body’s AF system to operate at full capacity.
