The Yongnuo YN 50mm f/1.8 DA DSM PRO is a lens designed for Fujifilm X-mount users who want sharp, high-end images without breaking the bank. Priced at under $300, this lens combines a solid build with features that set it apart from other lenses in its price range.
Coming to you from Dustin AbbottThis comprehensive video reviews Yongnuo 50mm f/1.8 PRO Lens. This lens is significantly different from Yongnuo’s non-PRO version, with a heavier, more solid build. It also comes with premium features like an internal digital stepping motor (DSM) and a custom ring that can switch between aperture control and manual focus. The metal construction, polished finish, and top-mounted LCD give it a feel that’s on par with higher-end lenses, making it a solid alternative to more expensive first-party options.
Optically, Abbott emphasizes the lens’s strong sharpness and image quality. Tested on a demanding 40-megapixel sensor, the lens performs well across the frame. It delivers consistent sharpness, even wide open at f/1.8, with only a slight softness in the corners. Stopping down to f/2 or f/2.8 improves contrast. Abbott also points to the lens’ ability to create smooth, attractive bokeh. However, the lens is prone to flare, especially when bright light enters the frame from the edges, so you’ll want to pay attention to your composition.
One of the main strengths of the Yongnuo 50mm f/1.8 is its autofocus capabilities. The DSM motor is quiet, making it ideal for both stills and video. However, Abbott notes that the autofocus system struggles to track fast-moving subjects, especially in continuous autofocus mode. This is more a limitation of the Fujifilm X system than the lens itself, but something to keep in mind if you plan on shooting action or sports.
Another valuable feature is the lens’ weather sealing, which should help it stand up to the elements. While it’s not as weather-sealed as some high-end lenses, it does offer some protection against dust and moisture, making it a good choice for outdoor shoots. The USB-C port for firmware updates is a handy addition, although access to it can be a bit tricky due to a small, removable cover. Check out the video above for Abbott’s full rundown.
