Standard Zoom Full-frame G-Master Lens:


   This professional lens is the best and right choice for making professional travel, landscape, portrait and event photos and is for those who are seeking the best optical performance. Internal XA element reduces image aberration and delivers very high resolution throughout in the entire zoom range and aperture range, as well as from corner to corner of all image media files.

Lens is Designed to achieve 50 line pairs/mm resolving power (See on PIC. 3)

   Achieving the spatial frequency of 50 lines pairs per millimeter at a lens’s widest aperture isn’t easy work. G-Master resolution is simply the highest in its class. Best resolution and other valuable design parameters yield outstanding reproduction of the most detailed subjects and scenes with superior contrast throughout each frame.

Surface precision in unthinkable and unattainable  nowadays granularity of 10 nanometers

   Built with 3 aspherical elements including a newly developed and essential ingredient for astonishing resolution – is a new XA (eXtreme Aspherical) lens element with better that 0.01-micron (10 nano-meters) surface precision.

   (See the differences between conventional and XA Lens on PIC. 4).

   The extremely precise XA element reduces aberration and delivers the ultimate resolution throughout the entire zoom range and aperture range, as well as from corner to corner of all image files.

 

Constant F2.8 max aperture maintains exposure and depth of field

  Constant F2.8 max aperture maintains exposure and depth of field regardless of the focal range you choose to zoom to. When changing your aperture to defocus the background, the areas out of the focal plane appear blurred. The “bokeh” effect of the blurred background can be enhanced with circular aperture blades successfully applied in this lens.

 

Nine-blade circular aperture contributes to gorgeous “bokeh” effect

   When changing your aperture to defocus the background, the light sources appear blurred. This ‘bokeh’ effect of the blurred background can be enhanced with circular aperture blades used in this lens.

   Conventional aperture blades have flat sides creating unappealing, polygonal shaped defocussed points of light. α lenses overcome this problem through a unique design that keeps the aperture almost perfectly circular from its wide-open setting to when it is closed by 2 stops. Smoother, more natural defocusing can be obtained as a result.

Using Super Sonic Wave Motor for Direct Drive SSM (DDSSM) for quiet, precise focusing

   High-resolution camera bodies demand absolute focus precision. The Direct Drive Super Sonic Wave Motor (SSM) focus system is more than up to the task for both stills and movies. DDSSM has the capability to position the large, heavy optical assemblies required by large-aperture lenses with pinpoint precision, offering many advantages for autofocus as well as manual focus.

  Manual focus response is quick, natural and makes work with the lens fully intuitive.

Nano AR Coating

   Sony’s original Nano AR Coating technology minimizes flare and ghosting, for dynamic range that achieves lifelike detail and gradation with advanced camera sensors. This precisely defined regular nanostructure allows accurate light transmission, contributing to high-quality images, even more so than with lenses that use coatings with an irregular nano-structure.

   The reflection suppression characteristic of the Nano AR Coating is superior to conventional anti-reflective coatings, providing a notable improvement in clarity, contrast, and overall image quality.

Dust and moisture resistant for robust reliability

   Sony’s standard lens sealing is augmented by a lens mount seal that maximizes resistance to dust and moisture for reliable operation in challenging environmental conditions.

   Sony designers and engineers insert additional details like rubberized rings (see PIC. 6) that are easy to operate at low temperatures, a zoom lock that prevents unwanted lens extension during transport, and a hood lock button, all add up to professional control and convenience.

ED and Super ED glass reduces flare and ghosting

   ED (Extra-low Dispersion) and Super ED glass elements (see PIC. 7) take axial chromatic aberration and chromatic aberration due to differences in magnification out of the picture, maximizing resolution and “bokeh” effect while leaving precisely rendered edges with no fringing or unnatural coloration (see PIC. 7).

Advanced simulation techniques help to control the “bokeh” right from design

   The G-Master series lens elevates resolution to unprecedented heights. Thanks to new technology specifically developed to accommodate more exacting tolerances required in the face of continually evolving camera body performance.

   Here is applied the most advanced optical technology by SONY available in innovative lens elements, improvements of optical path design, long list of advanced simulations, in-depth testing, and calibration, achieving image detail and sharpness that reveal the essence of every scene and subject.

 

Instant Auto/Manual Focus Selection

   Instantly and quickly switch between auto and manual focus via an AM/MF switch on the side of the lens. This makes operation faster and easier as you let the camera and lens focus for you, or decide to take control and manually focus on the precise point you chose.

 

Focus Hold Button

   Once you’ve adjusted focus to where you want it, and pressing the Focus to hold a button on the lens barrel (PIC. 9) it will keep the lens locked to that focusing distance.

   The preview function can also be assigned to this button through the camera’s custom settings.

Internal Focus maintains lens dimensions

   Only the middle groups of the optical system move to achieve focus, so the overall length of the lens does not change. Other important benefits include fast autofocusing and a short minimum focusing distance.

   The filter thread at the front of the lens does not rotate, which is convenient if you’re using a polarizing filter.
