As part of Sony's flagship G Master series, this lens is designed to achieve notably high resolution and sharpness through the correction of a wide variety of spherical and chromatic aberrations. G Master lenses feature robust and intuitive-to-handle physical designs to optimize both still photography and cine applications.

A popular 70-200mm telephoto zoom range designed for full-frame E-mount mirrorless cameras, this lens is also compatible with APS-C-format cameras where it renders a 105-300mm equivalent focal length range.

The constant f/2.8 maximum aperture offers consistent performance throughout the zoom range and lends greater control over focus position for shallow depth of field techniques. The new 11-blade aperture design operates silently and works together with the extreme XA aspherical element to suppresses onion ring bokeh, delivering a natural looking circular bokeh.

Two extra-low dispersion elements and two Super ED elements reduce chromatic aberrations and color fringing for increased clarity and color fidelity. Each optical surface has a Nano AR Coating II applied to reduce surface reflections, flare, and ghosting for increased contrast and color rendering in strong lighting conditions.

Four XD (Extreme Dynamic) Linear Motors ensure fast, precise, and accurate autofocus in both stills and video, with increased speed and improved tracking over the previous model, and reduced focus breathing, zoom shifting, and axis shifting for refined cine shooting.

Optical Steady Shot image stabilization helps to minimize the appearance of camera shake for sharper imagery when shooting handheld with slower shutter speeds. This stabilization system can also be combined with select camera's sensor-shift type image stabilization for more effective control of camera blur. An OSS mode switch offers selection between Mode 1 for general image stabilization suited to general shooting, a Mode 2 setting designed for panning movements, and Mode 3 for emphasizing framing stability when shooting moving subjects.

Designed with video applications in mind, flexible focus control is provided by features such as full-time DMF (Direct Manual Focus), Linear Response MF, and a focus-range limiter. An aperture ring with switchable clicks and an iris lock provides refined exposure control in different shooting conditions.

The lens barrel is equipped with three programmable focus control buttons, a focus mode switch, range limiter, iris lock, and aperture ring click selector to permit fast, intuitive operation of the lens while shooting.

The front lens element features a fluorine coating to protect against smudges and dust from adhering to the glass surface. Dust- and moisture-sealed design better permits working in harsh environments.

A removable, rotating tripod mount permits quick switching from horizontal to vertical shooting orientations.

The included lens hood features a flocked interior for reduce glare and an opening that allows convenient operation of separately purchased circular polarizing or other rotating filters.

Compatible with Sony's optional 1.4x and 2x teleconverters, this lens can be easily transformed into a 98-280mm or 140-400mm optic, respectively.

Normal-length prime is designed for full-frame Canon EF-mount DSLRs, however can also be used with APS-C models where it provides an 80mm equivalent focal length.

Exceptionally bright f/1.2 maximum aperture affords extensive control over depth of field for selective focus applications and also benefits working in low-light situations.

One aspherical element helps to suppress spherical aberrations and distortion for a high degree of sharpness and accurate rendering.

Super Spectra coating has been applied to individual elements to minimize ghosting and flare for greater contrast and color neutrality when working in strong lighting conditions.

A ring-type Ultrasonic Motor (USM), along with optimized focusing algorithms and a high-speed CPU, is employed to deliver fast, precise, and quiet autofocus performance as well as full-time manual focus override.

Rounded eight-blade diaphragm contributes to a pleasing out of focus quality that benefits the use of shallow depth of field and selective focus techniques.

As a member of the esteemed L-series, this lens is sealed against dust and moisture for working in inclement environmental conditions.
