Samyang AF 50mm f/1.4 AS UMC 50mm

The Samyang 50mm f/1.4 FE II adds autofocus and weather sealing to a beloved formula, all for a street price around $237. Bokeh and macro performance are outstanding, but AF speed is merely average and there's no stabilization. It's a phenomenal value for portrait and video shooters on a budget, less ideal for fast action.

Let's dig into what these scores mean in the real world. The 95th percentile macro rating stands out. With a minimum focus distance of 50mm, you can get shockingly close, and the nine-blade diaphragm renders those close-up details with a smoothness that is absolutely top of the charts. Combine that with the f/1.4 aperture, which itself lands in the 93rd percentile, and you've got a recipe for subject isolation that makes portraits pop even in messy backgrounds. The bokeh is genuinely beautiful, easily best-in-class for a lens under $500.

Optical performance overall sits at the 65th percentile, which is solid but not a standout. What that means in practice: center sharpness is excellent, especially stopped down just a hair, but the corners can get a bit soft wide open and there's some vignetting that requires a stop or two to clean up. The 54th percentile AF score is the reality check. The STM motor is quiet and smooth for video, making focus pulls feel cinematic, but it isn't lightning fast. For a fast-paced walkaround or event work, you'll feel the delay. And since there's no optical stabilization, you're relying entirely on your Sony body's IBIS, so handheld video on an unstabilized body like an a6000 series can get shaky.

Direct comparisons get a little weird because Samyang doesn't really compete with zooms, and our competitor list is full of them. The Tamron 17-70mm f/2.8 Di III-A VC RXD is a versatile workhorse with stabilization, but its bokeh can't match the Samyang's f/1.4 magic and its macro performance lags behind. The Viltrox Air 15mm F1.7 is a wide-angle prime that's fun for landscapes and astro, but it's a completely different tool. If you want one lens for travel flexibility, the Tamron wins. If you want shallow depth of field and dreamy portraits, the Samyang is the clear choice.

When you line it up against its true rivals, the Sony 50mm f/1.4 GM and the Sigma 50mm f/1.4 DG DN Art, the story gets sharper. The Sony is blazing fast to focus, nearly flawless optically, and costs around $1,400. The Sigma is a step down in AF speed but still faster than the Samyang, at about $900. The Samyang undercuts both by hundreds, sometimes over a thousand dollars, while delivering bokeh and macro that beat the Sigma and nearly match the Sony. What you lose is speed and corner performance. For the money, it's an absurdly good deal, but if you shoot weddings or fast-paced events, the Sony's reliability is worth the premium.

Here's the thing that keeps making us smile: the price. Our data shows a spread from $237 all the way up to an obviously erroneous $43,133, but the real street price sits at a point that should embarrass Sony and Sigma. When you can buy this lens for less than a good filter set for the Sony 50mm f/1.4 GM, the value proposition is hard to ignore. Even with its AF quirks, you're getting aperture and bokeh performance that often surpasses lenses in the $500 to $700 range.

The best deal we're seeing right now lands around that $237 mark, making it one of the cheapest autofocus f/1.4 lenses on any full-frame system. If you're a hobbyist who wants to experiment with fast glass without financial panic, or a professional who needs a backup 50mm that won't break the bank, this is a no-brainer. You sacrifice a bit of AF polish and absolute edge-to-edge sharpness, but you keep a whole lot of cash in your pocket.

The Samyang 50mm f/1.4 FE II is the lens a lot of Sony shooters have been waiting for. The first generation earned a cult following for its razor-sharp optics and creamy bokeh, but the lack of autofocus was a dealbreaker for many. This FE II adds a linear STM motor and weather sealing while keeping the price shockingly low, and that flips the script entirely. If you're a portrait shooter or a video creator who wants that f/1.4 dreaminess without selling a kidney, this thing is aimed right at you.

We pulled our database numbers and the early street pricing we're seeing is absurd, around $237 at some retailers. That is not a typo. It puts the lens in a completely different conversation than the $1,400 Sony 50mm f/1.4 GM or the $900 Sigma Art. Of course, a low price only matters if the glass delivers, and in a few key areas it absolutely does. The 94th percentile bokeh rating and 95th percentile macro performance are the kind of numbers you usually see on lenses costing four times as much.

But here's the part we need to talk about: autofocus. Samyang finally gave us AF, but our benchmarking puts it at the 54th percentile. That's about average, not bad, but it's the weak link in an otherwise stellar package. If you're coming from the old manual-only version, you'll be thrilled. If you're used to Sony's linear motors, you'll notice the difference. For still life, portraits, and deliberate video work, it's plenty. For erratic fast action, you might miss more shots than you'd like.

Action and wildlife shooters who need instantaneous, pinpoint autofocus should look elsewhere. The 54th percentile AF speed means this lens can hunt in low contrast and won't reliably track fast-moving subjects. Sports photographers and event shooters who can't miss a moment will be better served by the Sony 50mm f/1.4 GM or even a fast zoom with stabilization.

Also, if you rely on handheld video without a stabilized body, the lack of optical IS can leave you with jittery footage. In that case, a lens like the Tamron 17-70mm f/2.8 with VC is a smarter choice, trading the f/1.4 aperture for versatility and steadier shots.

If your main thing is portraits, product photography, or slow-paced cinematic video, the Samyang 50mm f/1.4 FE II is a ridiculously great buy. It'll give you that creamy background separation, let you get in close for detail shots that look almost macro, and you won't have to take out a loan. Paired with a Sony body that has decent IBIS, you'll get smooth footage and sharp stills, and the weather sealing means you can keep shooting when it drizzles.

But if you're a sports photographer, a wildlife shooter, or someone who needs autofocus that locks on and stays locked while a subject moves unpredictably, this lens's average AF will frustrate you. It's also not the best pick for travel if you want stabilization or zoom flexibility. In those cases, spending more on a stabilized zoom or saving for a Sony GM makes more sense. For everyone else, the Samyang 50mm FE II is the kind of lens that makes you feel like you got away with something.
