Finally, Yongnuo announces several E-mount lenses (for Sony cameras), the 50mm f/1.8 as well as the 85mm f/1.8.

Let’s start by talking about the first lens: the 50mm F1.8S DA DSM (the 85mm F/1.8S DF DSM can be found here).

Moreover, we can notice a new logo/name on the Yongnuo lenses: YnLens.

This is the first Yongnuo lens for Sony APS-C cameras with an E-mount. The construction seems better than the others 50mm F/1.8 from Yongnuo (for Canon and Nikon) which are starting to date.

The lens is autofocus, with a stepping motor called DSM (Digital Stepping Motor). Canon calls this motor STM and Nikon AF-P.

The lens has been officialized in April 2020, and already available on Chinese dealer websites but also on Amazon U.S.

The lens hood is included, although basic, it’s always a pleasure.

The 50mm f/1.8S DA DSM is an almost direct competitor to the Sony 50mm f/1.8 OSS for more than half the price.

The USB port will allow you to update the firmware, using a cable and software. You can find the latest firmware on our dedicated page.
