Sony Unleashes Fastest G Master Lens Yet with 50mm f/1.2


Sony has officially entered the realm of extremely fast glass with its newest addition to the G Master family: the FE 50mm f/1.2 GM lens. Not only does the new lens add one of the most popular prime focal lengths to Sony’s top-tier lineup, but it also becomes Sony’s fastest E-mount lens to date. The flexibility of the 50mm focal length and brightness of an f/1.2 aperture make this lens an ideal candidate for portraiture and fashion, whether working in the studio or out on location. The impressively compact and lightweight build of this lens—its length and weight match that of its ½-stop slower predecessor—should attract street, event, and even landscape photographers looking for a high-performing prime.

Sharp Focus and Soft Bokeh

To capture exacting images with razor-thin depth of field, the new G Master takes advantage of Sony’s latest advances in lens technology and consists of 14 elements arranged in 10 groups. Three XA (extreme aspherical) elements join forces to combat aberration, maintain corner-to-corner sharpness, and produce smooth out-of-focus areas. A newly developed 11-blade circular aperture further contributes to clean and natural bokeh, whether in the foreground or background of an image. Combine these attributes with a minimum focusing distance of 1.3' and maximum magnification of 0.17x and the lens becomes a solid option for capturing close-up subjects.

Fast AF and Intuitive Design

The 50mm f/1.2 utilizes four XD (extreme dynamic) motors for fast, precise, and quiet autofocusing. Responsive manual focusing permits quick and smooth adjustments when shooting stills and expanded creative possibilities when recording video. Like other G Master lenses, a focus mode switch is included on the side of the lens barrel for quick toggling between focus modes. New is the addition of a second focus hold button on the lens barrel, which can be customized to your preference. Familiar to G Master veterans is the inclusion of a de-click switch for the aperture, a useful feature when recording video.

Built to Last

Like past G Master lenses, the 50mm f/1.2 features hybrid metal-and-plastic construction to balance weight and durability while providing protection against dust and moisture. The front element features a fluorine coating to prevent fingerprints, dirt, water, and other contaminants from sticking to its surface.

How Does It Compare?

The FE 50mm f/1.2 GM is a major upgrade compared to Sony’s Planar T* FE 50mm f/1.4 ZA lens and a direct competitor to Canon’s RF 50mm f/1.2L USM and Nikon’s NIKKOR Z 50mm f/1.2 S lenses. One of the most impressive aspects of the new prime is how Sony was able to maintain the same size and weight as its f/1.4 model while adding 36% more optical surface to achieve an extra ½ stop of brightness. It matches the length and weight of Canon’s f/1.2, making them both lighter and smaller than Nikon’s version. From a usability standpoint, the Sony features more on-lens tactile controls than the Canon, while the Nikon offers a unique OLED display on the barrel of the lens.

Also New from Sony: Camera-Mount Bluetooth Wireless Audio

Sony’s announcement of the FE 50mm f/1.2 GM lens follows the release of a pair of audio upgrades aimed at mirrorless video shooters: the ECM-W2BT Camera-Mount Digital Bluetooth Wireless Microphone System and ECM-LV1 Compact Stereo Lavalier Microphone.

The ECM-W2BT was designed for vloggers, journalists, and other video content creators seeking an on-camera wireless mic solution. The system consists of a receiver that attaches directly to the MI shoe of compatible Sony cameras and a clip-on transmitter with built-in omnidirectional microphone for quick setup. Each features built-in rechargeable lithium-ion batteries that can last up to 9 hours when attached to the MI shoe or 3 hours on their own. Utilizing Bluetooth connectivity, the system can operate up to 650' in good visibility. Microphones are built into the transmitter and receiver, allowing the camera operator and talent to be recorded at the same time. A moisture- and dust-resistant design means you can use the system outdoors with confidence under less-than-ideal conditions.

For low-profile audio recording scenarios, the ECM-LV1 lavalier connects with the ECM-W2BT’s transmitter via a 3.3' cable and 3.5mm TRS connector, minimizing the visible footprint of your audio setup. The lav records stereo audio via two omnidirectional capsules. A foam windscreen is included to minimize noise during recording.
