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

Professional Super-Telephoto Zoom A long-reaching and highly versatile lens, the Sony FE 100-400mm f/4.5 GM OSS is the super-telephoto zoom built without compromise; it’s designed to meet the needs of the professional wildlife, birding, sports, and journalism photographers. Thanks to a portable design with internal zoom and focus, as well as the renowned G Master optical capabilities, this constant maximum aperture zoom offers the performance and rendering required for photographing small and distant subjects at high speeds with high precision. 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.
