The Yongnuo YN 50mm f/1.8 DA DSM PRO is a lens designed for Fujifilm X mount users who want sharp, premium images without breaking the bank. For less than $300, it combines a solid build with features that set it apart from other lenses in its price range.
Coming to you from Dustin Abbott, this comprehensive video reviews the Yongnuo 50mm f/1.8 PRO lens. The lens is notably different from Yongnuo’s non-PRO version, with a heavier, sturdier build. It also comes with premium features like an internal digital stepping motor (DSM) and a customizable ring that can be switched between aperture control and manual focus. The metal construction, sleek finish, and top-mounted LCD screen all give it a feel comparable to higher-end lenses, making it a solid alternative to more expensive first-party options.
In terms of optics, Abbott emphasizes the lens’ 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 minor softness in the corners. Stopping down to f/2 or f/2.8 improves contrast. Abbott also points out the lens’ ability to render smooth, attractive bokeh. However, the lens is prone to flare, especially when bright light enters the frame from the edges, so it's worth paying attention to your composition.
One of the key strengths of the Yongnuo 50mm f/1.8 is its autofocus. The DSM motor operates quietly, making it ideal for both photo and video work. However, Abbott notes that the autofocus system struggles with tracking fast-moving subjects, especially in continuous autofocus mode. This is more of a limitation of the Fujifilm X system than the lens itself, but it’s something to be aware of if you plan on shooting action or sports.
Another valuable feature is the lens' weather-sealing, which adds to its durability in outdoor conditions. While the sealing isn’t as extensive as some high-end lenses, it provides some protection against dust and moisture, making it a good option for outdoor shoots. The USB-C port for firmware updates is a handy addition, although accessing it can be tricky due to the small, removable cover. Check out the video above for the full rundown from Abbott.
