Manufacturer description #1

SAN DIEGO, April 22, 2025 /PRNewswire/ -- Sony Electronics Inc. introduces the FE 50-150mm F2 GM (SEL50150GM), the world's first telephoto zoom lens with a maximum focal length of 150 mm and F2 aperture. This lens features a standard focal length of 50mm at the wide-angle end and combines a constant aperture of F2 with high resolution comparable to that of a prime lens. This allows for a wide range of scenarios with just one lens for various situations and subjects. As part of Sony's renowned G Master series, the FE 50-150MM F2 GM offers an exceptional combination of high resolution and stunning bokeh, enhancing the imaging results for professionals using the Sony Alpha camera system.

"The FE 50-150MM F2 GM G Master marks a pivotal milestone in Sony's commitment to pushing creative possibilities," said Yang Cheng, Vice President of Imaging Solutions, Sony Electronics Inc. "By delivering a constant F2 aperture across its zoom range, this lens offers Sony Alpha users with an all-in-one solution that is comparable to multiple prime lenses, like a 50mm, 85mm, and 135mm. This innovation expands the versatility professionals need to capture remarkable imagery in both photography and video."

Exceptional Image Quality and Smooth F2 Bokeh

The G Master's internal optical design plays a crucial role in producing its exceptional image quality. By integrating two XA (extreme aspherical) elements, two Super ED (extra-low dispersion) glass elements, and three ED elements, the lens effectively suppresses aberrations, ensuring sharp, high-contrast imagery across the entire zoom range. Additionally, the floating focusing system enables a minimum focusing distance of 0.4m at the wide end and a maximum magnification of 0.20 for detailed shooting.

The FE 50-150MM F2 GM's constant F2 aperture creates beautifully smooth bokeh, making it an ideal choice for portrait, wedding, and event photographers aiming to isolate subjects with a shallow depth of field. A newly developed 11-blade circular aperture further enhances the signature G Master bokeh. When shooting videos, the lens delivers stunning cinematic results and exceptional clarity.

In addition, Sony's proprietary "Nano AR Coating II," applied uniformly across the entire lens surface, significantly reduces ghosting and flare even in backlit conditions, delivering clear and crisp imagery.

Internal Zoom and Compact Design

Measuring at approximately 7-7/8 inches (200 mm) in length and weighing approximately 47.3 ounces (1,340g), the FE 50-150MM F2 GM offers remarkable portability considering its impressive combination of wide zoom range and bright aperture. This lens is ideal for both handheld and gimbal use with its featured internal zoom design that maintains the lens's length and weight balance despite focal length changes. With its practical design, this lens serves as a versatile, all-in-one solution for those seeking a standard 50mm through 150mm telephoto range.

Fast and Precise Autofocus Performance

Equipped with four XD (extreme dynamic) linear motors and Sony's advanced control algorithms, the FE 50-150MM F2 GM delivers fast, accurate, and quiet autofocus (AF). This high-performance AF system is compatible with Sony's Alpha 9 III, supporting continuous shooting at up to 120 frames per second with full AF/AE tracking. With a fast AF system and a versatile 50-150 mm zoom range, the lens excels at capturing fast-paced indoor sports, portraits, and events.

Cinematic Video Production

Designed with filmmakers in mind, the FE 50-150MM F2 GM minimizes focus breathing and is compatible with Sony's Breathing Compensation feature on select Alpha cameras. Linear Response MF ensures intuitive manual focus control, while the lens's internal zoom design maintains stability even while zooming mounted on gimbals. Additionally, the XD linear motors operate quietly to prevent unwanted noise from being captured during recording.

Built for durability, the FE 50-150MM F2 GM features a robust dust- and moisture-resistant design. A fluorine coating on the front element repels contaminants, making it easy to clean and ensuring the lens remains in top condition even in challenging environments.

Manufacturer description #2

Developed for creators who want next-generation versatility and expression, this telephoto zoom is the world’s first with a maximum focal length of 150 mm and F2 aperture. Deep bokeh works with telephoto compression for creative portraits, and the large aperture is ideal for indoor events. All of this plus internal zoom in an agile lens that weighs just 1340 g (47.3 oz., without tripod base).

Innovative optical design and manufacturing achieve unprecedented performance. Two precision XA (extreme aspherical) elements in a state-of-the-art optical design plus meticulously controlled aberration deliver breathtaking resolution at all apertures, including F2. Two Super ED (Extra-low Dispersion) and three ED glass elements minimise chromatic aberration, while Nano AR Coating II suppresses flare and ghosting.

This large aperture telephoto zoom offers easy handling with a weight of just 1340 g (47.3 oz., without tripod base) and a length of 200 mm (7-7/8 in). Despite its large aperture it can be handheld with minimum stress. Internal zoom contributes to excellent balance that optimises handling for indoor sports or similar subjects. The 50-150 mm range allows uninterrupted shooting without the need for lens changes in many situations.

Four precision XD (extreme dynamic) linear motors drive the focus group for fast, accurate, quiet focusing that maximises the AF performance potential of modern camera bodies. Tracking easily keeps up with the 120 fps maximum burst speed of the α9 III and is consistently reliable even while zooming. This is a perfect lens for professionals whose jobs depend on getting the shot.

Focus breathing is effectively reduced for smooth movie imagery, and Linear Response MF allows precise manual focusing for maximum sharpness and resolution. Rack focus and zoom effects can be used with F2 depth of field to create natural transitions that guide the viewer’s eye. Critical focus for high frame rate 4K 120p/FHD 240p recording is easy, and the entire system operates with minimal noise and vibration.

Operability is enhanced by an aperture ring with click ON/OFF and lock switches, three assignable focus hold buttons, and a DMF switch that enables temporary switchover to manual focus while using AF. And although it is a relatively large lens, ample clearance is provided for the camera grip. The removable tripod foot has 1/4” and 3/8” screw holes, and a dust/moisture resistant design ensures maximum reliability.
