FE 100-400mm F4.5 GM OSS overview
The Sony FE 100-400mm F4.5 GM OSS is a 100–400mm f/4.5 zoom for full-frame cameras on Sony E-mount, announced by Sony in May 2026. 39 cameras we track take it without an adapter.
Going by its spec sheet, it suits wildlife and sport as well as travel. It is a weaker pick for low light without a tripod and travelling light.
New, it sells for A$5,814.89 to A$7,389 at the 4 stores we track in Australia that have it in stock. Over the last 90 days it has usually cost A$5,399 to A$6,297 new.
Worth comparing it with the Sony FE 100-400mm F4.5-5.6 GM OSS.
