Full-Frame E-mount. As a part of the FE line of lenses, the FE 100-400mm f/4.5-5.6 GM OSS is designed for Sony full-frame cameras. It’s also fully compatible with APS-C cameras, on which it’ll provide a 150-600mm equivalent focal length.

Pro-Grade Compact Telephoto Zoom. The FE 100-400mm f/4.5-5.6 GM OSS is a far-reaching telephoto zoom that’s great for sports, wildlife, and action photographers and videographers who are looking for some extra reach. The rounded nine-blade diaphragm helps create smooth bokeh when you’re using selective-focus techniques.

Image Stabilization. An Optical SteadyShot image-stabilization system minimizes the appearance of camera shake at all focal lengths, giving you sharp images even when you’re shooting hand-held at lower shutter speeds. The SteadyShot system will work with select cameras’ built-in sensor-shift image stabilization for even more effective blur control.

Direct Drive SSM Autofocus System. This internal focusing system provides fast, nearly silent, and highly accurate autofocus performance that’s great for still and video use. A dedicated focus hold button and AF/MF switch help to tailor focusing to your shooting needs. There’s also a manual aperture ring that can be “de-clicked” for smooth aperture adjustment when shooting video.

Advanced Optics. The FE 100-400mm f/4.5-5.6 GM OSS’s 16-group/22-element design includes one super extra-low dispersion element and two extra-low dispersion elements to minimize chromatic aberrations, and to produce clear, high-contrast images. A Nano AR coating keeps flare and ghosting at bay while maintaining color fidelity.
