    PRESS RELEASE

    Sony today announced two new G Master™ super telephoto prime lenses for the Alpha™ full-frame E-mount system, the FE 400MM F4.5 GM OSS with a focal length of 400 mm and the FE 600MM F6.3 GM OSS with a focal length of 600mm, both are the world’s lightest*1 lenses in their respective categories.

    The FE 400MM F4.5 GM OSS weighs approximately 994g and the FE 600MM F6.3 GM OSS approximately 995g, achieving the world’s lightest*1 design in their respective categories. Their lightweight design makes them suitable for dynamic shooting styles that involve exploring the environment to identify and capture photographic opportunities and subjects. In addition, their carefully optimised weight balance provides excellent control during handheld shooting, including situations that require photographers to continuously keep subjects framed or track moving subjects. These features broaden the flexibility of super telephoto photography for subjects such as birds, wildlife and sports.

    The lenses deliver the exceptional resolution and beautiful bokeh that define the G Master series across the super telephoto range, capturing distant subjects in fine detail. In addition, fast, precise and quiet AF performance enables photographers to quickly capture fast-moving subjects.
