Sony Australia has expanded its E-mount lens lineup with the new FE 100-400mm F5.6-8 OSS, a compact super-telephoto zoom lens designed to make wildlife, sports and travel photography more accessible without the bulk typically associated with long-range lenses.
The Hardware
Offering a versatile 100-400mm focal length, the new full-frame lens is aimed at photographers looking to capture distant subjects while keeping their setup lightweight. Weighing approximately 654g, the lens is easy to carry for extended shooting sessions, making it ideal for birding, aviation, motorsports, and outdoor adventures.
Despite its compact build, the FE 100-400mm F5.6-8 OSS features a modern optical design incorporating two Extra-low Dispersion (ED) glass elements and two aspherical elements to control chromatic aberration and deliver edge-to-edge sharpness throughout the zoom range. A rounded 9-blade aperture helps produce smooth, natural background blur for clear subject separation.
Autofocus is driven by dual linear motors, providing fast, precise, and quiet subject tracking. The lens supports high-speed continuous shooting up to 120 fps with continuous AF on compatible Alpha bodies, while built-in Optical SteadyShot (OSS) image stabilisation helps minimise camera shake when shooting handheld at maximum focal lengths.
The lens features a dust and moisture-resistant design for greater confidence when shooting outdoors, along with a zoom lock switch to prevent the lens extending during transport. It accepts 55mm filters and offers a minimum focusing distance of 1.5 metres, providing flexibility for both close telephoto subjects and distant action.
Design and Specs
Designed for outdoor reliability, the lens features a dust- and moisture-resistant construction alongside a zoom lock switch to prevent lens extension during transport. Onboard controls include a customizable focus hold button, a SteadyShot switch, and a focus mode/range limiter switch.
The lens accepts 67mm filters and boasts an impressive minimum focusing distance of 0.86 metres at the telephoto end (with up to 0.41x maximum magnification), making it surprisingly capable for close-up shots of flowers, details, and insects. It is also compatible with Sony’s 1.4x and 2.0x teleconverters, extending maximum reach up to 800mm (or 1200mm in APS-C mode).
Pricing and Availability
The Sony FE 100-400mm F5.6-8 OSS is available for pre-order in Australia from 5 August until 23 August 2026 and will go on sale from 24 August 2026 at a recommended retail price of AU$1,399.
Conclusion
The Sony FE 100-400mm F5.6-8 OSS proves that big reach doesn’t have to mean a heavy kit or a massive price tag. Delivering sharp glass, fast tracking, and built-in stabilisation in a sub-700g body, it’s a game-changer for hobbyists looking to capture distant action without being weighed down.
