The Sony FE 50mm f/1.4 GM Lens brings G Master optical performance to a compact, lightweight body built for photographers and videographers who need fast autofocus and smooth bokeh without added bulk. Weighing just 516 grams (18.2 oz), this full-frame prime pairs a wide f/1.4 maximum aperture with two XA (extreme aspherical) elements and one ED (extra-low dispersion) glass element. The result is sharp, high-contrast images from corner to corner with controlled chromatic aberration, even at wide apertures.

Sony FE 50mm f/1.4 GM Standard Prime Lens

Part of the G Master line of lenses, the Sony FE 50mm f/1.4 GM Lens is designed with advanced optics and elements to deliver professional-grade resolution and bokeh all from a compact and lightweight form factor. The fast and responsive Sony 50mm GM lens is an everyday lens with uncommon performance that maximizes the speed potential of Sony's Alpha series cameras, helping them keep subjects in focus, even when using a shallow depth of field.

Key Features of the Sony FE 50mm f/1.4 GM

Two high-thrust XD (extreme dynamic) linear motors drive the focus group for fast, precise, and near-silent autofocus. This design supports reliable subject tracking for both stills and video, including high frame rate recording up to 120 fps. Sony also includes focus breathing compensation support, which maintains a consistent angle of view when pulling focus during video work.

The 11-blade rounded aperture produces smooth, natural bokeh that separates subjects from their backgrounds. At f/1.4, the shallow depth of field isolates subjects effectively for portraits, documentary work, and low-light shooting. The XA elements help prevent "onion ring" artifacts in out-of-focus highlights, a common issue with less refined optical designs.

• Dedicated aperture ring with click/de-click switch and iris lock

Build Quality and Controls

The Sony FE 50mm f/1.4 GM measures 80.6 x 96mm and weighs 516 grams. This compact size makes it practical for handheld shooting and gimbal work without sacrificing optical quality. The lens shares filter threading with the FE 24mm f/1.4 GM and FE 35mm f/1.4 GM, allowing photographers to share 67mm filters across the trio.

Built to withstand the rigors of outdoor use, the Sony FE 50mm f/1.4 GM features a dust and moisture-resistant design, meaning you can use it with confidence in adverse conditions. So whether you're shooting in humid environments or dusty locations, you can rely on the Sony FE 50mm f/1.4 GM lens to deliver the performance you need to capture consistent images and videos.

The lens includes an aperture ring that runs from f/1.4 to f/16 in 1/3-stop increments with an "A" position for camera-controlled aperture. A de-click switch allows smooth, silent aperture changes during video recording. The iris lock switch, a first on any Sony prime lens, prevents accidental movement of the aperture ring. Two customizable focus hold buttons are positioned for convenient thumb access, and an AF/MF switch enables quick transitions between autofocus and manual focus.

Who Uses the Sony FE 50mm f/1.4 GM

The 50mm focal length remains one of the most versatile options for full-frame cameras. On Sony Alpha mirrorless cameras, it provides a natural field of view that works across multiple genres: portraiture, street photography, event coverage, documentary work, and general-purpose shooting. The f/1.4 aperture supports low-light work and shallow depth of field effects that draw attention to the subject.

Videographers benefit from the XD linear motor system, de-clicked aperture, and focus breathing compensation. The compact dimensions and consistent weight distribution make this lens practical for gimbal setups where balance is critical. Wedding and event photographers appreciate the reliable autofocus tracking for candid moments, while portrait photographers use the f/1.4 aperture to separate subjects from busy backgrounds.

Frequently Asked Questions

What is the minimum aperture on the Sony FE 50mm f/1.4 GM?

The minimum aperture is f/16. The aperture ring includes click stops in 1/3-stop increments from f/1.4 through f/16, plus an "A" position for camera-controlled aperture settings.

Does the Sony FE 50mm f/1.4 GM have image stabilization?

No, this lens does not include optical image stabilization. It relies on in-body image stabilization (IBIS) found in compatible Sony Alpha cameras. The lens does support Active Mode stabilization for handheld video when paired with cameras that offer this feature.

Is the Sony FE 50mm f/1.4 GM weather-sealed?

The body is designed with dust and moisture resistance. All seams are sealed, buttons and switches have silicone rubber gaskets, and a rubber ring seals the lens mount. The front element includes a fluorine coating that repels water, oil, and fingerprints. Sony does not provide a formal IP rating, but the construction provides reliable protection for typical outdoor conditions.

How does this lens compare to the Sony FE 50mm f/1.2 GM in size?

The f/1.4 GM is noticeably smaller and lighter. It weighs 516 grams compared to 778 grams for the f/1.2 version. The f/1.4 GM measures 80.6 x 96mm, while the f/1.2 GM measures 87 x 108mm. The lighter weight and smaller profile make the f/1.4 version more practical for extended handheld shooting and gimbal use.

Can I use this lens on APS-C Sony cameras?

Yes. When mounted on an APS-C sensor camera, the lens provides an equivalent field of view of approximately 75mm (due to the 1.5x crop factor). The lens projects a full-frame image circle, so it works on both full-frame and APS-C E-mount bodies.
