XA and Super ED elements deliver high resolution
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.
Narrow depth of field with breathtaking G Master 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 135-mm F1.8 lens.
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 AF control that is quiet and virtually free of vibration.
Floating focus mechanism for improved close-up capability
Although it is a 135-mm telephoto lens, a floating focus system that effectively controls aberration at all focusing distances has made it possible to achieve a minimum focus distance of just 0.7 m (2.3 ft) and a maximum magnification of 0.25x for close-up photography. Small accessories and other subjects can be captured with remarkable resolution and soft, beautiful background bokeh.
Superior imaging plus mobility, operability and reliability
The important features include customisable focus hold buttons, a focus range limiter, an aperture ring with switchable click stops, a dust/moisture resistant design2 and a fluorine coated front element. Overall, this is a lens that meets professional requirements for control and reliability for both stills and movies.

FEATURES
An F1.8 135-mm 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 135-mm 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 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.
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 its 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.
Customisable focus hold buttons on the side and top
Customisable focus hold buttons are provided on the side and top surfaces of the lens for easy access and convenient control when shooting in horizontal or vertical orientation — and at just about any angle. AF and other functions can be assigned to the focus hold buttons as required.
Focus range limiter
A focus range limiter switch (∞–1.5 m/2 m–0.7 m) makes it possible to limit AF operation to a predetermined range to maximise AF speed and prevent focusing on unwanted objects. The Far (∞–1.5 m) setting covers medium, head-and-shoulders, and full-length portraits, while the Near (2 m–0.7 m) setting is ideal for close-ups of the face or extreme close-ups of details
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.
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.
