This exemplary 100–400 mm super-telephoto zoom lens is ideal for wildlife, birds, sports, photojournalism and more. Maximum aperture is a constant f/4.5 and AF performance is fast and precise, easily maximizing the potential of Sony’s most advanced E-mount camera bodies. A lightweight inner-zoom design results in stress-free handling, while comprehensive control meets professional needs.

This fine lens delivers superb quality over a 100–400mm range, extendable to 800mm with an optional teleconverter. An ED XA (Extra-low Dispersion extreme aspherical) element plus XA, Super ED, and ED elements optimize chromatic and spherical aberration for high resolution throughout the zoom range. Maximum aperture is a constant f/4.5 while zooming. The ED XA and XA elements contribute to exquisite G Master bokeh.

Lightweight for fatigue-free shooting

Magnesium alloy parts and painstaking design have resulted in an overall weight of just 1,840g. That is remarkably light for a super-telephoto zoom, allowing users to shoot long sessions with minimum fatigue. Inner zoom minimizes centre-of-gravity shift when zooming, further enhancing handling and maneuverability. Even the zoom torque has been optimized to ensure smooth operation.

Advanced optical stabilization and professional control

Optical stabilization works with α in-body stabilization to achieve outstanding results. A function ring can be assigned to control Preset Focus for quick registration and recall of a specific focus point, APS-C/Full Frame switching that allows quick shifts to the equivalent of 1.5x zoom, or Power Focus. A zoom smoothness switch and security slot are also provided.

Rugged reliability in challenging conditions

In addition to a dust and moisture resistant overall design, the outer surface of the front element features a fluorine coating that prevents adhesion of fingerprints, dust, water, oil, and other contaminants. The coating also makes it easy to wipe the lens surface clean.
