Yongnuo YN 50mm f/1.4N E 50mm

The Yongnuo 50mm f/1.4N E gives you autofocus f/1.4 for under $250, and that's pretty remarkable. Sharpness gets good from f/2.8 up, and the build feels solid. But the autofocus motor is loud and the wide-open softness is real. It's a killer value for patient stills shooters, a no-go for video or silent work.

In our database, the autofocus system on this lens lands in the 81st percentile, which is well above average for lenses of this type. In the real world, that means the DC motor snaps into focus pretty quickly, rarely hunting in decent light. But that speed comes with a catch: the motor is loud. Multiple owners say it sounds like a small coffee grinder, and we're not going to sugarcoat it—if you're shooting a quiet wedding ceremony or recording video with the built-in mic, everyone will hear it. The AF/MF switch is a nice touch, and the lens did fine on older Nikon DSLRs without built-in focus motors because the DC motor does all the work.

Optically, the story is a mixed bag. Sharpness at f/1.4 is disappointing and matches the 43rd percentile optical ranking we have on file. Your images will show softness and a bit of veiling flare. By f/2.8, however, things tighten up nicely, and the contrast really starts to pop. The multi-layer coating helps with flare resistance, but it's not as effective as Nikon's Nano Crystal Coat. At its best—say, f/4 for a portrait—you'll get crisp eyelashes and pleasant bokeh, though the seven-blade diaphragm means out-of-focus highlights can take on a slightly geometric look at smaller apertures. Minimum focus is 0.45m, which is about a foot and a half, plenty for close-up details but not real macro work.

The closest competitor in the Nikon F world is the Nikon AF-S Nikkor 50mm f/1.8G. It's a touch more expensive, especially new, but it's remarkably sharp even wide open and the Silent Wave Motor is near-silent. You lose a stop of light gathering, but for video or quiet environments, it's the clear winner. Then there's the Nikon AF-S 50mm f/1.4G at about $450—better wide open, robust build, and silent AF. If you can afford it, the first-party glass outclasses the Yongnuo on almost every front except price.

Elsewhere, you'll find manual focus Chinese lenses like the Meike 50mm f/1.7 for even less money, but you give up autofocus entirely. The Samyang/Rokinon 50mm f/1.4 AS UMC is another option around $300-$400, but it's manual focus too and has a mixed reputation for sharpness wide open. The Yongnuo sits in a unique spot: affordable autofocus f/1.4 that works natively on Nikon DSLRs. It's not the best lens, but it's the best answer for a specific question—'what's the cheapest way to get autofocus f/1.4 on my Nikon?'

At $185 to $255, the Yongnuo 50mm f/1.4N E is basically the price of a Nikon AF-S 50mm f/1.8G but a full stop faster. That's wild. The f/1.8G is sharper at f/1.8, quieter, and smaller, but it can't open up to f/1.4 for low-light shooting or shallow depth of field. If you need that extra stop on a budget, this is the only autofocus game in town under $300. Compared to a used Nikon 50mm f/1.4G, which typically runs over $350, the Yongnuo saves you a meaningful chunk of change.

You are making trade-offs, though. The Nikon f/1.4G is sharper wide open, has a silent motor, and better coatings. The Yongnuo delivers about 70% of that performance for half the price. If you're a hobbyist who mostly shares images online, the Yongnuo gives you the f/1.4 look without the debt, and the sharpness you get at f/2.8 is plenty for big prints. It's a classic value proposition: accept the noise and a little softness, and you get an absurd amount of aperture per dollar.

The Yongnuo YN 50mm f/1.4N E is one of those lenses that makes you do a double take on the price tag. Here's a full-frame 50mm prime with an f/1.4 max aperture, autofocus, and a Nikon F mount for somewhere between $185 and $255 depending on where you look. That's a fraction of what Nikon charges for its own 50mm f/1.4, and it undercuts a lot of used options too. We've dug into the numbers and pored over owner feedback to see where Yongnuo cut corners, and where this thing actually shines.

Right away, this lens is aimed squarely at stills photographers who want that classic 50mm field of view and creamy background separation without draining their bank account. It lands in our database with an aperture score that surprises a lot of people—only 19th percentile. That sounds harsh for an f/1.4 lens, but the user sentiment and our own testing back it up: wide open, the images are soft and vignetting is noticeable. Stop it down to f/2 or f/2.8, though, and the performance flips into genuinely impressive territory. This is not a lens you buy for wide-open perfection.

What makes this lens interesting isn't the polish, it's the potential. It's a clone of an older optical design, but Yongnuo added a USB port for firmware updates and a DC motor that's quick on its feet. At its best, the YN 50mm f/1.4N E delivers sharp, contrasty images on a budget. At its worst, you'll be reminded why first-party lenses cost more. The question isn't whether it can take a good photo—it can—but whether you're willing to live with its quirks.

If you shoot video, record audio near your camera, or need silent operation for events, this lens will drive you up the wall. The autofocus noise is genuinely intrusive, and manual focus doesn't save it because the ring feels plasticky and imprecise. For those use cases, spend the extra cash on a used Nikon AF-S 50mm f/1.8G or a third-party lens with a stepper motor.

Astrophotographers and anyone who demands technically perfect wide-open sharpness should also pass. This lens cannot focus stars to crisp points at f/1.4, and that's a dealbreaker. Look for a manual Samyang/Rokinon 50mm f/1.4, or if budget allows, a used Nikon 50mm f/1.4G. The Yongnuo is a daytime portrait and street lens at heart—keep it in that lane and you'll be fine.

If you're a stills photographer who shoots portraits, street scenes, or low-light events and you don't mind the noise, the Yongnuo 50mm f/1.4N E is a fun and frugal addition to your bag. Keep it around f/2.8, and you'll pull sharp, vibrant shots that belie the price tag. The fast autofocus means you won't miss moments, and the build quality suggests it'll survive a few knocks. For the hobbyist exploring primes, this is a low-risk way to get the f/1.4 look.

On the flip side, if you're even thinking about video, walk away. The autofocus motor will ruin your audio, and the manual focus ring isn't smooth enough for reliable pulling. Astrophotographers should also steer clear—the one-star review we saw about stars refusing to become pinpoints matches what we've read elsewhere. Opt for a Nikon 50mm f/1.8G or, for astro, a good manual Samyang instead. The Yongnuo is a stills-only lens, and embracing that reality is key to being happy with it.
