Sony has announced the FE 50-150mm f/2 G Master, a new full-frame E-mount lens in its flagship trinity series. It is the first telephoto zoom lens to offer a maximum focal length of 150mm alongside a constant f/2 aperture.
The FE 50-150mm f/2 GM joins Sony’s G Master lineup, and like the rest of that series, it’s built to offer both high resolution and smooth bokeh.
Sony FE 50-150mm f/2 G Master Specifications
According to Sony, the lens covers several classic focal lengths used by professionals, such as 50mm, 85mm, and 135mm, in a single package. The aperture (f/2) remains consistent across the zoom range, so it’s suitable for users who frequently switch between wide, medium, and short telephoto shots without needing to swap lenses.
Internally, Sony has used a combination of advanced optics, including two XA (extreme aspherical) elements, two Super ED (extra-low dispersion) elements, and three ED elements. These are intended to control aberrations and improve sharpness and contrast across the frame.
There’s also a floating focus system that helps the lens maintain a 0.4m minimum focusing distance at the wide end, with up to 0.20x magnification.
The lens also benefits from Sony’s Nano AR Coating II, which helps reduce flare and ghosting in backlit conditions. A circular 11-blade aperture is designed to enhance the overall bokeh quality.
Physically, the lens measures around 200mm in length and weighs about 1,340 grams. Thanks to its internal zoom design, the lens doesn’t extend when zoomed in, which helps keep weight balance consistent.
Autofocus is handled by four XD linear motors and is supported by Sony’s AF algorithms. Sony says the lens is capable of maintaining fast and accurate autofocus even when shooting at 120fps with the Alpha 9 III. It also supports focus breathing compensation and includes Linear Response MF for more intuitive manual focus control during video recording.
The FE 50-150mm f/2 GM is dust and moisture-resistant, with a fluorine coating on the front element to help keep it clean.
Price and Availability
The Sony FE 50‑150mm f/2 GM will go on sale in June 2025 for £3,800 / €4,400. That puts it firmly in the high-end category, but given its specs and build quality, it’s clearly aimed at working professionals who need the flexibility of a zoom with the performance of primes.
