San Diego, CA—The new flagship of Sony Electronics’ full-frame G Master lens series is a super-telephoto prime: the Sony FE 600mm f/4 GM OSS (model SEL600F40GM). The lens was announced along with the FE 200–600mm f/5.6–6.3 G OSS super-telephoto zoom lens (SEL200600G).
The new 600mm is Sony’s longest reaching prime lens. Moreover, it incorporates the company’s most advanced optical and mechanical technologies.
The FE 600mm f/4 GM OSS weighs in at 6.71 pounds and features a balanced design. As a result, it gives professional sports, wildlife and news photographers another option for capturing subjects at great distances.
“With two new lenses announced, our growing E-mount lens lineup now includes 33 full-frame models and 51 lenses in total,” said Neal Manowitz, deputy president, Imaging and Professional Solutions Americas, Sony Electronics. “The tenth model from our flagship G Master series, the new 600mm f/4 raises the bar for speed, mobility and control in a super-telephoto prime lens.
“Combining the extensive 600mm reach with features like 20-fps shooting and AF/AE calculations at 60 times per second on the α9 or extremely high resolution, high-speed performance on the α7R III allows professional photographers to create images that were simply not possible to capture before.”
Sony FE 600mm f/4 GM OSS Specs
To best take advantage of the autofocus systems of Sony’s latest full-frame E-mount cameras, the new lens uses two extreme dynamic (XD) linear motors. They drive the lens’s focus group to provide fast, precise AF and subject tracking. In addition, the motors are supported by specially developed motion algorithms to minimize lag and instability, as well as control noise levels.
This large aperture super-telephoto prime lens also features “outstanding contrast and resolution maintained all the way to the corners of the image,” added Manowitz. Its optical design includes a large extreme aspherical (XA) element that suppress common telephoto lens aberrations. In addition, three fluorite elements help minimize chromatic aberration and suppress color bleeding. It is also coated with Sony’s Nano AR coating to suppress unwanted reflections, glare or ghosting.
In addition, Sony’s latest bokeh simulation technologies and XA element are utilized to control spherical aberration and help achieve pleasing bokeh. Moreover, the lens uses an 11-blade circular aperture mechanism to contribute to the quality of bokeh in images. Also, inherited from Sony’s FE 400mm F2.8 GM OSS, the new 600mm lens features a design that is not front heavy. This is to ensure quicker, more precise panning when shooting handheld or on a monopod. The lens is also compatible with Sony’s 1.4x and 2.0x E-mount tele-converters,
Furthermore, the lens integrates a number of hard controls. They include customizable focus-hold buttons in four different locations on the lens barrel; the buttons are programmable to control features. There is also a full-time DMF switch to engage manual focus at any point; also, a focus ring provides linear response MF for fine manual focus.
The lens also incorporates optical stabilization and three mode settings. The mode 3 setting uses an advanced algorithm to enable easier framing when following moving subjects. It also features a function ring with selectable preset and function settings. Additionally, a drop-in filter slot accepts ø 40.5mm ND and other filter types. It also accepts Sony’s optional VF-DCPL1 drop-in circular polarizing filter.
Moreover, the lens can withstand the harsh conditions of sporting events and wildlife photography. Made of magnesium alloy, it has a lightweight carbon fiber hood. It is dust and moisture resistant, and its fluorine coating resists dirt and fingerprints.
The Sony FE 600mm f/4 GM OSS lens ships in August 2019. It will retail for $13,000.
