Sony Alpha Sony SEL100400MC FE 100-400mm F4.5 GM OSS FF E Mount Lens

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 maximising 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 optimise 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.

*SEL20TC and SEL14TC teleconverters supported.

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 α9 III body, reliable AF tracking is achieved at bursts of up to 120 fps.** Focus breathing and zoom related focus and axial shifts are minimised for smooth, professional looking movie imagery.

*Compared to the FE 100-400mm F4.5-5.6 GM OSS (SEL100400GM) mounted on an α9 III body.
**Sony tests. Continuous burst speed may be lower in some shooting conditions. Continuous burst speed may vary depending on the lens used in AF-C focus mode.

Lightweight for fatigue-free shooting

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

Advanced optical stabilisation and professional control

Optical stabilisation works with α in-body stabilisation 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.

*Functions that can be assigned to the Function Ring will depend on the camera used. Refer to the corresponding camera Help Guide for details.
**Power Focus is initially assigned to the Function mode by default. See Sony's support web page for function and body compatibility information: https://support.d-imaging.sony.co.jp/www/cscs/lens_body/index.php?lang=en&area=gb

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.

*Not guaranteed to be 100% dust and moisture proof.
