The 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.

ED 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 the background and foreground bokeh.

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.

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.

Dust and moisture resistance maintains reliability in harsh environments

A dust and moisture resistant design provides the protection needed for reliable operation in challenging outdoor environments.

Easy de-click for movies

An aperture ring provides the type of immediacy and response that professionals need for both still photography and videography. An Aperture click switch allows the aperture ring click stops to be engaged or disengaged as required. Engaging the click stops provides tactile feedback that can make it easier to gauge how much the ring has been adjusted by feel and is, therefore, a good choice for still photography. When the click stops are disengaged the aperture ring moves smoothly and quietly, providing seamless, silent control for moviemaking.

Fluorine coated front element

The front lens surface features a fluorine coating that resists fingerprints, dust, water, oil, and other contaminants, and makes cleaning easier if any contaminants do become attached to the lens.

Focus range limiter

A focus range limiter switch (∞ ~ 1.5m / 2m ~ 0.7m) makes it possible to limit AF operation to a predetermined range to maximise AF speed and prevent focusing on unwanted objects. The Far (∞ ～ 1.5m) setting covers medium, head-and-shoulders, and full-length portraits, while the Near (2m ~ 0.7m) setting is ideal for close-ups of the face or extreme close-ups of details
