Autofocus and Handling
The 400-800mm f/6.3-8 G OSS features two linear motors for fast and accurate autofocus, capable of keeping up with the Alpha 9 III’s 120 fps burst rate and up to 240 fps in video. The internal zoom mechanism keeps the lens balanced while zooming, improving stability for handheld use. The zoom ring has a short throw for quick adjustments, making it easier to track fast-moving subjects.
Stabilization and Build
The lens includes Sony’s Optical SteadyShot (OSS) stabilization, reducing motion blur for handheld shooting. When paired with a Sony Alpha camera that has in-body image stabilization, stability improves further. The lens has a non-removable tripod mount foot, allowing for smooth rotation between portrait and landscape orientation.
Designed for outdoor shooting, the dust- and moisture-resistant build enhances durability, while a fluorine-coated front element helps repel dirt and smudges.
