Sony launches 600mm f4 GM OSS Super-telephoto lens

Sony 600mm f4 GM OSS Super-telephoto prime lens:

This is the first time Sony has launched a 600mm prime lens. And in doing so, it is now fully competing with Canon and Nikon in terms of super-telephoto lenses. There was a time when Sony was a pretender and all the leaders were Canon and Nikon. With the success of its mirrorless cameras, now Sony is poised to take a leap with its super-telephoto offerings.

According to Sony nomenclature all lenses which bear the G Master brand bear high standards with very good contrast across the lens at high spatial frequencies.

The Sony 600mm f4 GM OSS lens weighs 3040 grams. Along with the 400mm f2.8 the 600mm f4 will give professional wildlife photographers, sports shooters another option.

The Sony 600mm f4 GM OSS lens comes in the Sony E mount and covers 35mm full frame. The angle of View is 4°10′.

The Sony 600mm f4 lens has 24 elements in 18 groups. The lens has a large aperture XA (extreme aspherical) element and three Flourite elements. This will help to minimize axial chromatic aberration as well as lateral chromatic aberration. This results in very fine subject details. Sony has also included Nano AR coating which will help in reducing ghosting and unwanted reflections. The front lens element has a fluorine coating so that it becomes easy to clean finger prints and smudges.

The lens has 11 aperture blades for a smooth bokeh. At the minimum, it focuses at 14.8 feet or 4.5m away. It has a filter of dia 40.5 mm. This lens comes with image stabilization which is branded as Optical SteadyShot. 5 axis image stabilization is available when used with Sony alpha cameras.

The lens aperture can be set from f4 to f22. It has four customizable multi-function focus hold buttons. After focus is adjusted, pressing one of the four hold buttons will ensure that the lens holds focus in that focus plane.

Sony has included two Extreme Dynamic linear motors for fast and precise autofocus.

Dimensions: The Sony 600mm f4 GM OSS lens is 163.6mm wide and 449 mm long (6-1/2 inches wide x 17-3/4 in. long)

Price: In US it is priced at 12998 US Dollars.

Sony Introduces the New Super-Telephoto 600mm F4 G Master™ Prime Lens

Sony today announced another impressive addition to its flagship full-frame G Master series lens line-up, the new FE 600mm F4 GM OSS super-telephoto prime lens (model SEL600F40GM).

Sony’s longest reaching prime lens, the new 600mm includes many of the company’s most advanced optical and mechanical technologies, producing exceptional image quality with extraordinary focusing speed and precision. The lightest in its class[i], weighing in at only approx. 3040g, the FE 600mm F4 GM OSS features an extremely balanced design to ensure the best possible shooting experience. Along with the acclaimed FE 400mm F2.8 GM OSS lens, the new 600mm gives professional sports, wildlife and news photographers more options for capturing subjects at great distances with extreme accuracy and detail.

“With two new lenses announced today, our growing E-mount lens line-up now includes 33 full-frame models and 51 lenses in total. The 10th model from our flagship G Master series, the new 600mm F4 raises the bar for speed, mobility and control in a super-telephoto prime lens,” said Yann Salmon Legagneur, Director of Product Marketing, Digital Imaging at Sony Europe. “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 allow professional photographers to create images that were simply not possible to capture before.”

Fast, Precise and Quiet Autofocus[ii]

To take best advantage of the highly evolved autofocus systems of Sony’s latest full-frame E-mount cameras, the new FE 600mm F4 GM OSS lens features two XD (extreme dynamic) Linear Motors that drive the lens’ focus group to provide fast, precise AF and reliable subject tracking. These motors are supported by specially developed motion algorithms to minimise lag and instability, as well as to control noise levels, resulting in exceptionally quick, accurate and quiet autofocus performance, allowing the lens to capture dynamic, fast moving athletes or wildlife with ease.

Superb G Master Image Quality and Bokeh

As a member of Sony’s flagship G Master series lenses, this new large aperture super-telephoto prime lens features an incredible level of image quality and detail, with outstanding contrast and resolution maintained all the way to the corners of the image. The unique optical design includes a large XA (extreme aspherical) and an ED (extra-low dispersion) element that effectively suppress all common telephoto lens aberrations, plus three fluorite elements that help to minimise chromatic aberration and suppress any amount of colour bleeding. Sony’s latest bokeh simulation technologies and XA element are also utilised to control spherical aberration and help achieve exquisite bokeh.

The lens also features an 11-blade circular aperture mechanism that contributes to the high quality of bokeh in images, and has been coated with Sony’s original Nano AR coating to suppress any unwanted reflections, glare, or ghosting in images.

The new FE 600mm F4 GM OSS is compatible with Sony’s 1.4x and 2.0x E-mount tele-converters, producing outstanding imaging performance at extended focal lengths[iii] while maintaining fast, precise AF performance.

Lightweight, Balanced Design

Weighing in at only approx. 3040g, the new super-telephoto prime lens is the lightest in its classi, providing a level of portability and manoeuvrability that has never been achieved before in a lens of its style. Based on technology from the acclaimed FE 400mm F2.8 GM OSS lens, the lightweight design of the new 600mm lens is achieved through the usage of three fluorite elements, with a reduced number of elements deployed at the front of the barrel. Magnesium alloy is also used throughout the lens to help minimise weight and bulk.

Also inherited from FE 400mm F2.8 GM OSS, the new 600mm lens features a lens design that is not front-heavy, reducing moment of inertia that resists rotation, ensuring quicker, more precise panning when shooting handheld or on a monopod.

Durability, Reliability and Control

To withstand the harsh conditions of sporting events and wildlife photography, Sony’s new FE 600mm F4 GM OSS is built with a durable magnesium alloy and a strong, lightweight carbon fibre hood. The lens is also dust and moisture resistant[iv], and its front element is coated with fluorine to resist dirt and fingerprints.

There is also an ample number of hard controls on the lens, including customisable focus-hold buttons in four different locations on the lens barrel, which can be programmed for control of features, if desired. There is also a ‘Full-Time DMF’ switch to immediately engage manual focus at any point, and a focus ring that features Linear Response MF for fine, responsive manual focus.

Additionally, the new lens includes built-in optical stabilisation for dynamic action and three different ‘Mode’ settings, including a Mode 3[v] setting with an advanced algorithm that ensures easier framing when following moving subjects. It also features a function ring with selectable ‘Preset’ and ‘Function’ settings, and a drop-in filter slot that accepts ø 40.5mm ND and other filter types, as well as the optional VF-DCPL1 Drop-in Circular Polarising Filter. The VF-DCPL1 filter can be rotated to achieve the desired polarisation while installed in the lens.

Pricing and Availability

The FE 600mm F4 GM OSS will ship in Europe in August 2019, priced at approximately €14,000. USA price is 12988 USD.
