Sony FE 100-400mm f/4.5 GM OSS Lens, Bundle with 95mm Filter Kit, Cleaning Kit

Superb optics and AF in a superlative super-tele zoom
This exemplary 100-400 mm super-telephoto zoom lens is ideal for wildlife, birds, sports, photojournalism and more. Maximum aperture is a constant F4.5 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.

Outstanding G-Master resolution and bokeh from 100 to 400 mm
This fine lens delivers superb quality over a 100-400 mm range, extendable to 800 mm 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 F4.5 while zooming. The ED XA and XA elements contribute to exquisite G Master bokeh.

Fast, precise AF effortlessly tracks active subjects
Advanced algorithms and four of Sony's XD (extreme dynamic) Linear Motors drive the floating focus groups for up to 3x faster AF. Tracking performance has been improved by up to 50%. With the a9 III body (sold sep.), reliable AF tracking is achieved at bursts of up to 120 fps. Focus breathing and zoom related focus and axial shifts are minimized for smooth, professional looking movie imagery.

Lightweight for fatigue-free shooting
Magnesium alloy parts and painstaking design have resulted in an overall weight of just 1,840g (approx.). That is remarkably light for a super-telephoto zoom, allowing users to shoot long sessions with minimum fatigue. Inner zoom minimizes center-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 lens stabilization works with a 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 optical 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.
