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 S$5,699 in Singapore (TK Foto).

Worth comparing it with the Sony FE 100-400mm F4.5-5.6 GM OSS.
