Sony FE 400-800mm F6.3-8 G OSS Announced – Super-Telephoto Zoom Lens

Right alongside the launch of the FE 16mm F/1.8 G ultra-wide-angle prime lens, Sony also launched a super-telephoto zoom lens: the FE 400-800mm F/6.3-8 G OSS. This massive piece of glass has the longest focal length amongst Sony E-mount lenses and will be perfect for bird, wild, or sport photography and filmmaking. So, let’s take a closer look at it!

Back in 2019, Sony released the Sony FE 200-600mm f/5.6-6.3 G OSS and the massive FE 600mm f/4 GM OSS telephoto prime lens. While the super-telephoto zoom lens market can seem relatively “niche,” Sony continues to expand their Sony E-Mount lineup, which will now cover all focal lengths from 12mm up to 800mm with this new FE 400-800mm F/6.3-8 G OSS.

Sony FE 400-800mm F/6.3-8 G OSS – features

The Sony FE 400-800mm F/6.3-8 G OSS is a massive lens with an outside diameter of 11.9cm/4.68in, a length of 34.6cm/13.6in, and a weight of 2.47kg/5.22lbs with the tripod collar. As you can tell, this is the kind of lens you bring on purpose, as it takes a lot of room in a backpack/case.

This super-telephoto zoom lens covers full-frame image sensors. With a wide zoom range that goes from 400mm with a maximum aperture of F/6.3 to 800mm at F/8, it has the most extended focal length of the Sony E-Mount lens lineup. Furthermore, if you use it with the optional 1.4x teleconverter, you can reach 1120mm at F/11 and even 1600mm at F/16 with the 2.0x teleconverter.

Lenses are one of the most important creative tools in cinematography. Learn the foundations of optics and gain the ability to design lens tests, collaborate with technicians and understand technical specifications.

On the lens body, you’ll find two large rings, one for the zoom and one for the focus. When you zoom in/out, the lens doesn’t extend or retract; it has an internal zooming design, which almost doesn’t change the center of gravity of your setup when zooming.

There is also a plethora of buttons and switches, including:

Three focus hold buttons.
One AF/MF focus mode switch.
A full-time direct manual focus (DMF) switch. You can directly set full-time DMF On/Off with this switch without needing to access it in the camera’s menu.
Since this is an OSS lens, it features Optical SteadyShot image stabilization. You’ll find one OSS On/Off switch and one OSS mode switch to select from three stabilization modes.
A focus range limiter with three settings: full, 10m – near, and 8m to infinity.

At the bottom of the Sony FE 400-800mm F/6.3-8 G OSS, you’ll find a tripod mount with one 1/4″-20 and one 3/8″-16 mounting point. The lens comes with a lens hood that has a filter window.

Primarily designed to shoot outdoors, this super-telephoto zoom lens is dust- and moisture-resistant. All seams are sealed, buttons and switches have silicone rubber gaskets, and a rubber ring seals the lens mount.

In terms of performance, the autofocus system features two linear motors, which should provide fast, precise, and quiet AF performances. If you switch to manual focus, the focus ring has a linear response for precise adjustments.

Last but not least, Sony claims that the FE 400-800mm F/6.3-8 G OSS has nearly zero focus breathing, and it supports breathing compensation with compatible cameras.
