Unsparing application of Sony's most advanced optical technologies has produced a large-aperture prime telephoto lens that delivers outstanding resolution even at F1.8, plus exquisite bokeh that is a hallmark of the G Master series.
One Super ED (extra-low dispersion) glass element and one ED glass element are strategically positioned to compensate for axial chromatic aberration that is often a problem in large-aperture telephoto lenses, achieving impressive sharpness. In addition to improving resolution, this configuration minimizes color fringing that can occur in background and foreground bokeh.
Sony's innovative XD (extreme dynamic) linear motors also play an important role, making it possible to maintain focus on moving portrait subjects, performers on stage, or similarly dynamic subjects with impressive speed, precision, and reliability, while also providing quiet, low-vibration AF control.
