Product Overview
The Sony FE 50-150 mm f/2 GM (model SEL50150GM) is a groundbreaking telephoto zoom lens in the G Master series, offering a constant f/2 aperture across its 50–150 mm range. This makes it the world’s first full-frame zoom lens with this speed, combining versatility with prime-level low-light performance, exceptional sharpness, and creamy bokeh. It’s designed for professional photographers and hybrid creators working in fields such as portraits, weddings, indoor sports, and cinematic video.
Exceptional Optics & Image Quality
To deliver top-tier performance, the lens uses two Extreme Aspherical (XA) elements, two Super ED elements, and three ED elements. This sophisticated optical construction minimizes spherical and chromatic aberrations, delivering crisp high-resolution results across the zoom range. A Nano AR Coating II further reduces flare and ghosting, even in challenging backlit conditions.
Constant f/2 Aperture for Creative Control
The constant f/2 maximum aperture provides exceptional control over depth of field, enabling subject isolation and dreamy background separation throughout the entire zoom range. An 11-blade circular diaphragm enhances the quality of out-of-focus areas, giving smooth and natural bokeh — ideal for portraits, event photography, and cinematic video.
Fast & Precise Autofocus
Focus performance is powered by four XD (Extreme Dynamic) linear motors, providing lightning-fast, accurate, and nearly silent autofocus. This enables reliable subject tracking, especially on fast-moving or unpredictable subjects. The lens also supports Linear Response Manual Focus, allowing intuitive and precise manual control, which is particularly valuable for video.
Professional Handling & Controls
Internal Zoom & Focus Design: The lens maintains its physical length during zooming and focusing, which helps with balance (especially on gimbals) and preserves handling consistency.
Aperture Ring: Comes with a de-click switch and lock, so you can choose between smooth, quiet iris pulls or discrete, clicky steps.
Zoom Smoothness Switch: Lets you adjust the torque of the zoom ring (smooth or tight) – a useful feature for video work or photography.
Three Focus Hold Buttons + DMF Switch: Provides extended focus control, and allows instant switching from auto to manual focus without losing your AF settings.
Robust Build & Durability
Built with dust- and moisture-resistant sealing, the FE 50-150 mm f/2 GM is ready for professional use in challenging environments. The front element has a fluorine coating, making it easier to clean and more resistant to fingerprints, smudges, and water.
Telephoto Reach with Portability
Despite its brightness, the lens is relatively compact for its speed, measuring around 200 mm in length and weighing 1,340 g. Its balance and internal zoom make it surprisingly usable handheld for events, portraits, and travel. Additionally, it features a removable tripod foot with both 1/4" and 3/8" mounting options, giving flexibility for different support systems.
Perfect for Hybrid Creators
This lens is built for both stills and video:
Cinematic Output: Reduced focus breathing and support for Sony’s Breathing Compensation make this lens well-suited for video.
High-Speed Shooting: Compatible with fast cameras for burst shooting (e.g., up to 120 fps on certain bodies) thanks to its powerful AF and optical design.
Balanced Weight: The internal construction and zoom design make it stable on gimbals without excessive front-weight.
