Sony's new 70-200mm f/4.0 G OSS FE is a high quality telephoto zoom in a handy size for Sony E Mount Cameras. Being an FE lens it covers full frame sensors but it's equally useful on APS sized sensor Alpha Mirrorless (or earlier NEX) E System Cameras. The lens is an impressive combination of optics and technology packaged into a compelling solution for photographers wanting a high performance telephoto zoom that is reasonably compact and handles better than a f/2.8 telephoto zoom.
Lighter and more compact E system telephotos zooms exist but no other offer the flexibility of an f/4 aperture all the way through for or the same level of optical performance. The f/4 aperture allows increased background blur for stand out portraits and makes shooting in low light easier. Image quality is exceptional thanks to a highly corrected optical formula of 21 elements in 15 groups including one Super ED glass element, two ED glass elements, one Aspherical element, and two Advanced Aspherical elements as well as state of the art Nano-AR anti reflective coating, and a 9 bladed circular aperture mechanism all working together to deliver excellent sharpness, contrast, and bokeh.
The Optical Steady Shot system detects camera/lens movement and moves lens elements to offset the movement which reduces loss of sharpness and allows easier use of slower shutter speeds. Two Steady Shot modes are provided via a switch on the barrel: Mode 1 for normal shooting and Mode 2 for panning while shooting.
The Internal focus design uses dual linear motors for responsive accurate focus. A focus distance limit switch provides the option of the full focus range or a narrower range of infinity to 3 meters for even faster focusing at distance.
Exterior construction is solid and features a weather resistant design. A removable rotating tripod collar is a standard accessory.
Available accessories include the ALC-SH133 Lens Hood.
Sony FE 70-200mm G OSS is a full frame telephoto zoom lens with a constant f/4 maximum aperture. The FE lens offers many features to achieve the best photo with high quality details, in addition to a rugged dust and moisture resistant build. To compensate for blurred images, the Optical SteadyShot image stabilization counteracts unwanted image blur caused by camera shake during hand-help shooting. Its Super Sonic Wave Motor (SSM) produces smooth, silent and fast responding auto focusing. The internal focusing lens has a unique lens design that keeps the aperture almost perfectly circular from it wide-open setting to when it is closed by 2 stops for a more smoother natural defocusing result. Incorporating aspherical and extra dispersion lens elements to reduce spherical aberration and chromatic aberration to deliver superior contrast and quality across the entire image field. The incorporated Nano AR coating allows precise light transmission contributing to high-quality images and delivers an overall improvement to clarity and contrast. The lens also features a focus range limiter to set a limit on the focusing range and focus hold button to keep the lens barrel locked on the selected focusing distance.
