The Sony FE 70-200mm f/2.8 GM OSS Lens represents another step forward in photographic technology. This G Master 35mm, full-frame, telephoto zoom lens is a great choice for professional photographers who require the best optical performance. A standard zoom lens is a lens in which the focal length varies. A zoom lens is also one that maintains focus even with focal length of the subject-matter changes. Zoom lenses provide the user with a convenient, go-to lens of variable focal length. The G Master design combines extraordinary sharpness and smooth Bokeh in one lens. It is not easy to achieve spatial frequency of 50 lines pairs per millimeter at a lens's widest aperture and produce smooth bokeh at the same time, but that is Sony's baseline for G Master design. Unprecedented resolution and other demanding design parameters yield outstanding reproduction of the most detailed subjects and scenes.
Fast AF
Two heavy focus groups are rapidly and precisely positioned by separate actuators: a powerful ring SSM (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.
11-Blade Circular Aperture
Sony's circular aperture design has traditionally employed up to 9 blades, but this lens incorporates an 11-blade circular aperture that takes bokeh quality to new levels of smooth beauty with natural looking highlights.
