Sony YONGNUO 50F1.8S DA Lens, Auto Focus F1.8 Large Review

If you're a Sony shooter looking for a cheap, fast prime lens, the Yongnuo 50mm f/1.8 is probably on your radar. For around $110, you get a stabilized 50mm lens with a bright f/1.8 aperture, which is a pretty tempting combo for portraits or low-light shooting. It's a compact lens at just 249 grams, and it's compatible with a wide range of Sony E-mount cameras, from full-frame A7 models down to APS-C bodies like the A6000 series. People often ask, 'is this lens good for video?' The built-in stabilization helps, and its scores suggest it's decent, but it's not its strongest suit. It's really built for photographers who want that classic 50mm look without breaking the bank.

The performance story here is a bit of a mixed bag, which the percentile rankings make clear. Where this lens really shines is in close-up work. Its macro score is in the 92nd percentile, which is excellent for a non-macro lens, meaning you can get some surprisingly detailed close-up shots. The built-in stabilization is also top-tier, landing in the 90th percentile, which is a huge help for handheld shooting in lower light. But the trade-off comes in overall optical quality and autofocus. The optical score is only in the 33rd percentile, so don't expect tack-sharp corner-to-corner detail, especially wide open. The autofocus, at the 47th percentile, is just okay. It's not the fastest or most reliable, especially in challenging light, though Yongnuo says they've improved low-light focusing with a firmware update.

At $110, the value proposition is hard to ignore. You're getting a stabilized f/1.8 lens, which is a feature set Sony's own 50mm f/1.8 doesn't even have. The main question is whether you prioritize cost and stabilization over outright sharpness and snappy autofocus. If your budget is super tight and you shoot a lot of static or slower-paced subjects, this lens makes a lot of sense. If you can stretch your budget a bit, you might find better overall image quality elsewhere.

The most direct competitor is probably the Meike 55mm f/1.8, which often sits in a similar price bracket. The Meike generally has better-reported autofocus and optical performance, but it lacks image stabilization. So it's a trade-off: do you want sharper photos and better AF (Meike), or do you want the help of stabilization for handheld shooting (Yongnuo)? Compared to the more expensive Sony FE 50mm f/1.8, the Yongnuo wins on price and has stabilization, but the Sony lens has more reliable autofocus and slightly better optics. For APS-C users, the Viltrox 35mm f/1.7 is another alternative, giving you a more standard field of view on a crop sensor.

So, should you buy the Yongnuo 50mm f/1.8? If you're a beginner or a budget-conscious photographer who wants to experiment with a fast prime and really values having image stabilization, this is a solid gamble. It's fantastic for close-ups and okay for general use. But if you need reliable, fast autofocus for moving subjects or demand the absolute best image sharpness, you'll likely be frustrated. For the price, it's a fun lens with one standout feature (stabilization), but you are making clear compromises in other areas.
