Yongnuo YN 50mm F/1.8S DF DSM Lens for Full Frame Sony E-Mount Cameras Announced

Yongnuo has just announced a new affordable 50mm lens compatible with Sony E-mount full-frame cameras: the Yongnuo YN 50mm F/1.8S DF DSM. This compact and lightweight lens features two user-assignable function buttons and will join the already available 35mm and 85mm DF DSM prime lenses.

Chinese manufacturer Yongnuo is known for making affordable third-party lenses for DSLR and mirrorless cameras, but they are yet to release their YN455 Android-based MFT camera.

Last year, the company released a 50mm F/1.8 DA DSM lens for Sony E-mount cameras, but this lens only covers APS-C sensors. This time, Yongnuo is back with the YN 50mm F/1.8S DF DSM that covers full-frame sensors.

Yongnuo YN 50mm F/1.8S DF DSM features

The YN 50mm F/1.8S DF DSM (75mm equivalent on Sony APS-C mirrorless cameras) is compatible with every Sony E-mount camera. Moreover, as its name suggests, this autofocus lens features a Digital Stepping Motor for fast and silent focusing performances.

The YN 50mm F/1.8S DF DSM also features an AF/MF mode switch. In addition, this lightweight lens – 395g/0.87lbs – also has two user-assignable buttons close to the lens barrel. These buttons are useful if you quickly need to turn on/off functions like Focus Hold and even trigger recording.

On the lens mount, you’ll find a USB Type-C port for future firmware updates.

Lens design

The lens design of the Yongnuo YN 50mm F/1.8S DF DSM consists of eleven elements in eight groups with “six special optical elements,” according to the company. The aperture diaphragm has nine rounded blades, which should give you a smooth bokeh.

The minimum focusing distance is 45cm/17.72in, and the front filter diameter is 58mm.
