XA and Super ED elements deliver high resolution
XA (extreme aspherical) lens elements, with Super ED (extra-low dispersion) and ED glass, precisely arranged in an advanced optical design, correct aberrations, while the floating focus mechanism combined with aberration corrections ensures the highest possible resolution is maintained throughout the image and at every focus distance.
Shallow depth of field with stunning G Master background bokeh
The extremely high surface precision of XA elements, meticulous control of spherical aberration during both design and manufacturing stages, and an 11-blade circular aperture combine to create the stunningly smooth, elegant background bokeh of the G Master series, maximizing the creative potential of the shallow depth of field available with this 135mm F1.8 lens.
XD linear motors in front and rear deliver fast, precise, quiet autofocus
Sony's innovative XD (extreme dynamic) linear motors deliver reliable focus on moving portrait subjects, stage performers, and other dynamic subjects, with impressive speed, precision, and reliability, as well as quiet autofocus control with minimal vibration.
Floating focus mechanism for enhanced close-ups
Although a 135mm telephoto lens, the floating focus system with reliable aberration control at all focusing distances makes a minimum focusing distance of 0.7 meters (2.3 ft) and a maximum magnification of 0.25x possible for close-up shots. Small objects and other subjects are captured with stunning resolution and beautiful, soft background bokeh.
Outstanding image quality, portability, operability, and reliability
With customizable focus hold buttons, focus range limiter, aperture ring with switchable click stops, dust and moisture-resistant design, and a fluorine-coated front element. A lens with professional control and reliability for both stills and movies.
