An F1.8 135mm prime with superb resolution, bokeh, and AF
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.
XA and Super ED elements deliver high resolution even at F1.8
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.
Big, beautiful, natural bokeh
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 maximises the creative potential of the narrow depth of field available with this 135mm F1.8 lens.
D glass elements control colour aberration
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 minimises colour fringing that can occur in background and foreground bokeh.
Dual front and rear XD linear motors achieve fast, precise, quiet AF
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.
Nano AR Coating enhances flare resistance
Sony's original Nano AR Coating technology provides an effective solution, suppressing internal reflections that can lead to flare and ghosting so that optimum contrast and clarity are achieved in the widest possible range of shooting conditions.

Durable, lightweight magnesium alloy
The lens barrel chassis is constructed of a durable, lightweight magnesium alloy. The hardness of the alloy helps to maintain optimum optical precision and reliability, while it's lightness contributes to reduced overall weight.
Excellent response and fine linear focus control
The focus ring features Linear Response MF, allowing precise control and instantaneous response when focusing manually for stills or movies. Focus responds linearly to focus ring rotation so that the camera accurately follows operator input in a way that feels similar to mechanically coupled systems.
