XA (extreme aspherical), Super ED (extra-low dispersion) glass, and ED glass elements precisely deployed in an advanced optical design effectively correct aberration, while a floating focus system works with these aberration correction measures to ensure that the highest possible resolution is maintained right out to the image edges throughout the lens's focus range.
The extremely high surface precision of XA elements, careful control of spherical aberration at both the design and the manufacturing stages, and an 11-blade circular aperture all come together to produce spectacularly smooth, elegant G Master bokeh that maximizes the creative potential of the narrow depth of field available with this 135mm F1.8 lens.
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 AF control that is quiet and virtually free of vibration.
