Sony FE 50-150mm f/2 GM Lens
The Sony FE 50-150mm f/2 GM lens enters the photography landscape as a groundbreaking innovation, uniquely positioned to serve professional and advanced enthusiasts who demand exceptional performance in both still photography and video. As the world’s first full-frame zoom lens to feature a constant f/2 aperture extending to 150mm, this lens breaks new ground in optical design and practical functionality.
Traditionally, photographers and videographers had to choose between speed, reach, and image quality when selecting a zoom lens. However, with the introduction of this Sony lens, the compromise between brightness and focal length is eliminated. The constant f/2 aperture across the entire 50-150mm range not only enhances light-gathering capabilities in challenging lighting conditions but also enables consistent exposure and artistic control over depth of field throughout the zoom range.
This focal range is particularly beneficial for those working in environments where flexibility is essential—portrait sessions, event coverage, or even documentary-style filmmaking. The lens spans the traditional 50mm short telephoto starting point through to a robust 150mm medium-telephoto reach. On a Sony camera like the Sony A9 III or A1 II, the lens pairs seamlessly to provide a powerful tool for both still and motion capture, fully leveraging the high-speed autofocus systems and tracking performance these cameras are known for.
Incorporating a sophisticated optical design with 19 elements arranged in 17 groups, the lens utilizes a mix of extreme aspherical (XA), Extra-low Dispersion (ED), Super ED, and standard aspherical elements. This precision-engineered optical layout is crafted to reduce chromatic aberration, suppress color fringing, and ensure edge-to-edge clarity at all focal lengths. The result is sharpness and resolution that align with the demanding standards of Sony’s G Master (GM) series.
In autofocus performance, the Sony FE 50-150mm f/2 GM lens shines with four XD (extreme dynamic) linear motors. These motors enable responsive, silent, and precise focus transitions that keep up with fast-moving subjects—a must-have for professional sports and wildlife photography, or any scenario where reliability and speed are non-negotiable. Whether used for rapid bursts on a Sony A9 III camera or for real-time Eye AF in video on the Sony FX3, focus tracking is consistently accurate and unobtrusive.
From a physical standpoint, this lens is engineered to support professional fieldwork. Its robust construction features weather sealing against dust and moisture, ensuring dependable performance in outdoor and unpredictable shooting conditions. Despite its feature set and optical complexity, the lens remains relatively compact for its class, thanks to Sony’s advanced miniaturization of internal components and optical innovations.
