Sony unveils lightweight FE 100-400mm F5.6-8 OSS lens with extendable reach and affordability

Sony introduces the compact and versatile FE 100-400mm F5.6-8 OSS lens, offering long-range capabilities at an accessible price point and lighter weight, promising a new option for wildlife and sports photographers.

Sony has added a new super-telephoto zoom to its Alpha E-mount line-up with the FE 100-400mm F5.6-8 OSS, a full-frame lens aimed at photographers who want long reach without carrying a heavy optic. Weighing about 654 grams, it sits in the lighter end of the category and is pitched as a practical option for wildlife, sports and other distant subjects. Digital Camera World said the lens is being positioned as a relatively affordable way into super-telephoto shooting.

The lens covers a 100mm to 400mm range and uses two extra-low dispersion glass elements and two aspherical elements to help control chromatic aberration and preserve sharpness across the zoom range, according to Sony’s announcement. It also has a nine-blade circular aperture for smoother background blur, a minimum focusing distance of 0.86 metres at the long end and 1.13 metres at the wide end, and a maximum magnification ratio of 0.41x for close-up work.

For autofocus, Sony says the lens uses a linear motor drive for fast, quiet performance and supports high-speed continuous shooting when paired with the Alpha 9 III, reaching about 120 frames per second with autofocus and auto-exposure tracking. Built-in optical image stabilisation is included, along with support for the camera body’s Active Mode and coordinated stabilisation features, as well as breathing compensation for video work. The lens also adds a customisable focus hold button, a focus mode and range switch, a zoom lock switch, dust and moisture resistance and a hood to reduce flare and ghosting. Sony Alpha Rumors reported that the focus limiter has been folded into the AF/MF switch.

Sony says the lens can be extended with an optional teleconverter to reach 800mm, or 1,200mm when used in APS-C mode. That gives it more reach than its size might suggest and helps explain the interest from budget-conscious photographers, especially when compared with far more expensive long lenses. By contrast, Sony’s own 100-400mm G Master model sits in a different class altogether, with a constant F4.5 aperture and a far heavier 1,840-gram build, underscoring how this new F5.6-8 lens is aimed at a more accessible segment of the market. In Malaysia, Sony says it will go on sale from mid-August 2026 at a recommended price of RM3,499.
