The Sony FE 100-400mm f4.5–5.6 GM OSS is an exceptionally powerful full-frame super-telephoto zoom. Boasting Sony's G Master quality and resolution, each image is incredibly sharp, crisp and clear. With outstanding AF to keep up with fast-paced sports or unpredictable wildlife and a compact design, this lens is great for enthusiasts and professionals alike.
Extraordinary detail and bokeh in one lens
G Master design combines extraordinary sharpness and smooth bokeh in one lens. It’s not easy to achieve spatial frequency of 50 lines pairs per millimeter at a lens' widest aperture and produce smooth beautiful bokeh at the same time, but that’s Sony's baseline for G Master design. Unprecedented resolution and other demanding design parameters yield outstanding reproduction of the most detailed subjects and scenes with superior contrast throughout every frame. G Master resolution is simply the highest in its class.
Uncompromised G Master Design and Performance
The complex design features 22 lens elements configured in 16 different groups, including one Super ED (Extra-low Dispersion) and two ED glass elements, all of which work together to minimize chromatic aberration and ensure the ultimate resolution from corner to corner. The lens also has Sony’s original Nano AR coating, which is particularly useful for shooting sports scenes or wildlife, as it reduces unwanted reflections, flare and ghosting.
Fast, Quiet, Precise Focusing
In order to realize the maximum AF performance of a camera like the α9 and keep up with fast-moving action, common with sports and wildlife photography, the new FE 100-400mm GM super telephoto zoom lens features a double motor system. The Direct Drive Supersonic Wave Motor (DDSSM) drives the heavy front focus lens group, while the Double-linear motor system enables rapid acceleration of the main lens group to capture sudden subject motion. High precision positioning control and a newly optimized AF algorithm ensure the subject is found and focused on quickly, while the combination of the double linear motor and Direct Drive SSM actuator ensures fast, precise focusing, and quiet operation. In addition, the Double-linear motor system ‘oscillates’, to quietly achieve pinpoint focus when shooting movies.
High Performance Image Stabilization
High-performance Optical SteadyShot image stabilization is built right into the lens for sharp, blur-free images with a wide range of subjects and handheld shooting. The stabilization lens is driven by a linear motor for fast, precise compensation. Additionally, 5-axis image stabilization becomes available when used with α series cameras that feature built-in image stabilization
Aspherical Lens Dramatically Reduces Spherical Aberration
Aspherical lens design dramatically reduces spherical aberration while also reducing lens size and weight. Spherical aberration is a slight misalignment of the light rays projected on the image plane. This is caused by differences in refraction at different points on conventional spherical lenses which degrade image quality in large-aperture lenses. Specially shaped “aspherical” elements near the diaphragm restore alignment of light rays at the image plane, maintaining high sharpness and contrast even at maximum aperture and can also be used at other points in the optical path to reduce distortion. Well-designed aspherical elements can reduce the total number of elements required in the lens, thus reducing overall size and weight.
ED and Super ED Glass Reduces Flare and Ghosting
ED (Extra-low Dispersion) and Super ED glass elements take axial chromatic aberration caused by differences in magnification, out of the picture. The 100-400mm GM Super telephoto zoom lens incorporates one Super ED and two ED glass elements to maximize resolution and bokeh, while leaving precisely rendered edges with no fringing or unnatural colouration.
Focus Hold Button, Programmable for Multiple Functions
The focus hold button not only performs its primary function to lock focus when recomposing, but can be customized to a number of other functions depending on your needs. In addition to Focus Hold, these custom functions include: Eye AF, AF On, Aperture Preview, Shot Result Preview or Bright Monitoring.
Zoom Torque Adjustment Ring
The 100-400mm GM has a zoom torque adjustment ring – a first for Sony α – allowing the user to adjust the level of torque in the ring to zoom faster or slower depending on their shooting style.
In order to satisfy the extensive demands of customers craving lighter, smaller and more portable super telephoto lenses, the FE 100-400mm GM weighs in at a mere 49.3 ounces (1,395 grams), making it among the lightest in its class and an ideal fit for Sony’s wide range of compactly designed cameras
