A hallmark of the G Master line is outstanding optical performance with both high sharpness and smooth bokeh. Using a new design, the FE 70-200mm f/2.8 GM OSS II promises corner-to-corner sharpness across the entire zoom range—even when shooting wide open at f/2.8. Along with that, a newly designed 11-blade aperture helps create soft, pleasing bokeh.
- Fast f/2.8 constant aperture allows users to capture images in dim lighting conditions and with a shallow depth of field.
- Two ED (extra-low dispersion) and two Super ED elements, including one aspherical ED element, effectively suppress chromatic and spherical aberrations.
- Two aspherical lenses, including one extreme aspherical lens (XA), minimize distance-related aberrations and also reduce onion ring bokeh.
- Nano AR Coating II controls flare and ghosting with support from a new optical design that reduces internal reflections.
- An 11-blade aperture diaphragm helps create smooth, circular bokeh at all aperture settings.
Optimized for Video
Taking cues from their cinema division, Sony has optimized the 70-200mm II for video. Changes include a dramatic reduction of focus breathing and focus shift, improved autofocus performance, and a Linear Response MF system to ensure consistent, natural-feeling operation. Full-time Direct Manual Focus (DMF) also makes it easy to make quick adjustments using the focus ring while in AF modes.
The exterior design of the lens also sees some big changes. One clear example is the addition of a physical aperture ring that was not present on its predecessor. Users will be able to de-click this ring at the flip of a switch for smooth iris control during shooting. This provides shooters with independent controls for focus, zoom, and iris.
