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.
