Description — Sony SEL400F28GM
The Sony FE 400mm f/2.8 GM OSS is a prime super telephoto lens designed for the Sony E mount and built to cover full-frame sensors. With a fixed 400mm focal length and a maximum aperture of f/2.8, it delivers strong light-gathering performance at an extended reach — a combination that is highly valued in fast-action and wildlife photography contexts. The lens features optical image stabilization, which provides meaningful assistance when working at long focal lengths where camera shake is more pronounced.
Shooters can choose between autofocus and manual focus depending on their shooting style and subject matter. The filter thread is 40.5mm, which is a conveniently compact size for a lens of this specification. The lens weighs 2,897g, which reflects the engineering required to achieve f/2.8 performance in the super telephoto prime class and should be factored into any decision about shooting style and support equipment.
Designed specifically for Sony E mount mirrorless cameras, this lens is a dedicated tool for photographers who require serious reach and aperture performance from their Sony system.
