Key Features
Premium G Master Optics: Engineered with a complex 22-element, 16-group design featuring one Super ED and two ED (Extra-low Dispersion) glass elements. This heavily suppresses chromatic aberration, ensuring striking corner-to-corner sharpness even at 400mm.
Fast and Tenacious AF: Driven by an optimal combination of a double linear motor and a Direct Drive SSM (DDSSM) system, it delivers rapid, precise, and whisper-quiet autofocus tracking, ensuring you never miss a decisive moment.
Class-Leading Close-Up Performance: Features a remarkable minimum focus distance of just 0.98m and a 0.35x maximum magnification, allowing for stunning tele-macro shots of flowers and insects with beautiful background bokeh.
Zoom Smoothness Adjuster: A dedicated mechanical ring allows you to adjust the torque of the zoom ring. Set it to 'Tight' to prevent zoom creep during transport, or 'Smooth' for rapid focal length changes.
Built-in Optical SteadyShot (OSS): Integrated high-performance image stabilization heavily compensates for camera shake, delivering sharp, blur-free images even when shooting handheld at extreme telephoto lengths.
Teleconverter Compatible: Fully supports SONY 1.4x (SEL14TC) and 2.0x (SEL20TC) teleconverters. With the 2.0x teleconverter, you can achieve a massive focal length of up to 800mm while retaining excellent autofocus performance.
