Sony makes 100 – 400 mm full-frame zoom lens 80% cheaper and 65% lighter

Sony is expanding its lens lineup with a third 100–400 mm zoom lens. However, while the two older models were relatively fast for a telephoto zoom lens with a maximum aperture of f/4.5, the new model has a maximum aperture ranging from f/5.6 to f/8, depending on the focal length. This also makes it more difficult to use teleconverters, which effectively reduce the lens’s light-gathering ability even further.
This decision offers significant advantages in terms of the lens’s price and weight. With a list price of $850, the new lens is $3,450, or 80 percent, cheaper than the Sony FE 100–400 mm f/4.5 GM. Weighing 654 grams, the new lens is also about 1.2 kilograms, or 65 percent, lighter. The lens is 16.4 cm long with a diameter of 7.8 cm. Despite its lower price, Sony has opted for a complex design consisting of 15 elements in 10 groups and includes Optical SteadyShot (OSS).
Two ED lenses and two lenses with aspherically ground surfaces are designed to deliver high image quality across the entire zoom range. With a minimum focus distance of 0.86 meters, the lens achieves a maximum magnification of 0.41. The lens barrel features three sliders that can be used to lock the zoom, switch between autofocus and manual focus, and turn image stabilization on and off.
Pricing and availability
The Sony FE 100–400 mm f/5.6–8 OSS full-frame zoom lens will be released in late August 2026 at a suggested retail price of $850.
