Sony FE 100-400mm f/4.5 GM OSS Lens

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.

G Master Optical Performance

Sony's G Master designation is reserved for its highest performing optics, those that offer the greatest sharpness, smoothest bokeh, utmost speed, and best overall performance. This 100-400mm f/4.5 checks all of these boxes as it sets out to be a single lens replacement for several telephoto primes.

• Constant f/4.5 maximum aperture is more intuitive than the 100-400mm f/4.5-5.6 GM predecessor, offering faster performance at the long end of the range while still contributing to a portable, handholdable design.
• Bright-enough design is suitable for working in ambient conditions, especially when paired with the OSS, and it also offers greater control over depth of field and subject-background separation.
• ED XA, XA, Super ED, and ED elements yield high sharpness and smooth rendering that suits distant and backlit subjects, especially when working with busy backgrounds and strong lighting.

• Nano AR Coating II suppresses flare for rich contrast and bright colors in a variety of lighting conditions.
• Floating focus design maintains high image quality throughout the focusing range, resulting in matched sharpness from infinity to the 2.1' minimum focusing distance.
• Rounded 11-blade diaphragm results in smooth, circular bokeh quality.

High-Speed AF, Reliable OSS

Primarily designed for speed, precision, and reliability, the focusing and stabilization systems benefit wildlife, sports, and journalism applications. Additionally, the lens is well-suited to hybrid applications, including wildlife and sports videography.

• Four XD (extreme dynamic) linear motors generate fast and responsive AF performance that's equally quiet and smooth. The focusing system is compatible with continuous shooting speeds up to 120 fps or high-speed video recording at up to 240 fps.
• Compared to the previous 100-400mm f/4.5-5.6 GM, this lens's AF speeds are approximately 3x faster, tracking performance has improved by 50%, and subject tracking is more accurate thanks to new algorithms.
• Internal focusing design promotes quicker focusing speeds and maintains the lens length during use.
• Internal zoom maintains the overall length of the lens during operation, as well as keeps a consistent center of gravity for easier use on a tripod, especially with gimbal heads.

• Focus breathing has been greatly reduced optically and the lens supports the Breathing Compensation function in select cameras to effectively eliminate angle of view shifts while changing the zoom position.
• Maximum magnification of 0.25x, along with the 2.1-4.9' minimum focusing range, suits working with close-up subjects at near-macro magnification.
• Manual aperture ring offers tactile exposure control and the ring can be de-clicked for smooth and silent iris pulls or it can be locked in the 'A' position for camera-based aperture switching.
• The lens weighs about 4 lb, however much of this weight is at the rear of the lens for a balanced design that promotes comfortable handheld use.
• An advanced Optical SteadyShot image stabilization system ensures sharp imagery while shooting handheld at even the longest focal lengths. Multiple modes are available, including standard (Mode 1), panning (Mode 2), and moving subjects (Mode 3).
