FE 400mm F4.5 GM OSS overview

The Sony FE 400mm F4.5 GM OSS is a 400mm f/4.5 prime for full-frame cameras on Sony E-mount, announced by Sony in September 2026. 39 cameras we track take it without an adapter.

Going by its spec sheet, it suits wildlife and sport. It is a weaker pick for low light without a tripod.

Stores we track in Singapore list it, but none has it in stock today.

Worth comparing it with the Sigma 500mm F5.6 DG DN OS | Sports.
