Samyang 24mm f/1.4 ED AS UMC Wide-Angle Review

So you're looking at a fast, wide prime lens for your Nikon full-frame or APS-C camera. The Samyang 24mm f/1.4 is a bit of a specialist. It's not the lens you grab for a casual walk-around day, but when you need that ultra-wide field of view and the ability to suck in tons of light, it's got you covered. Think dramatic landscapes, tight interior shots, or environmental portraits where you want to show off the scene.

Honestly, this lens is built for photographers who know exactly what they're getting. At 776g, it's a hefty piece of glass. You feel that weight on the camera, and it's a constant reminder that this is a tool for specific jobs. The lack of autofocus and weather sealing means you're getting a pure, manual-focus optical instrument. It's not trying to be everything to everyone.

What makes it interesting is that f/1.4 aperture on a 24mm lens. That combination is less common than you'd think. It lets you shoot in really dim conditions without cranking the ISO sky-high, and it gives you the potential for some beautifully shallow depth-of-field even on a wide-angle. It's a creative choice, not just a technical one.

The numbers tell a clear story. This lens scores in the 88th percentile for aperture, which is its main party trick. That f/1.4 opening is massive for a wide-angle. In practice, it means you can handhold shots in a dimly lit bar or capture the Milky Way without a star tracker much more easily than with a slower lens like an f/2.8. The 83rd percentile optical score suggests the glass itself is sharp and renders colors well, especially when you stop down a bit from wide open.

Where the performance takes a hit is in the conveniences. The autofocus score sits at the 49th percentile, which basically means it doesn't have any—it's manual focus only. And with no image stabilization (43rd percentile), you're relying on your own steady hands or a tripod in slower light. The 72nd percentile macro score is decent for a wide-angle, but that 9.8-inch minimum focus distance isn't letting you get super close to tiny subjects. This lens performs brilliantly at the specific tasks it's designed for, but it asks you to do more of the work.

At around $388, the Samyang 24mm f/1.4 sits in an interesting spot. You're getting pro-level aperture specs and optical quality for a fraction of the cost of a Nikon or Sigma equivalent with autofocus. The trade-off is clear: you pay less, but you give up autofocus, sealing, and potentially some build refinement.

It's a fantastic value if your shooting style is deliberate and you don't mind manual focus. For astrophotography, controlled landscape work, or studio interiors, the savings are huge. But if you need autofocus for events or street photography, that low price tag suddenly comes with a big asterisk.

Let's stack it up against a couple of the competitors. The Viltrox 35mm f/1.7 for Z-mount is cheaper and has autofocus, but it's a 35mm focal length (less wide) and is designed for mirrorless cameras, not Nikon F-mount DSLRs. The Sony 24-240mm f/3.5-6.3 is the polar opposite: a superzoom that's incredibly versatile for travel, but its variable, slower aperture means it can't touch the Samyang in low light or for shallow depth-of-field.

The real comparison is against other manual focus wide-aperture primes. Against something like a used Rokinon 24mm f/1.4 (often the same lens with a different badge), it's a toss-up. You're really comparing price and maybe minor optical tweaks. The key takeaway is that the Samyang sacrifices convenience for pure optical capability at a low price. A zoom like the Panasonic 14-140mm will be far more flexible, but it will never give you that f/1.4 look.

If you're a landscape shooter, astrophotographer, or someone who loves slow, deliberate manual focus work, this lens is a steal. The image quality you get for under $400 is hard to beat, and the f/1.4 aperture opens up creative possibilities most wide zooms can't match. Just be ready for its weight and the lack of autofocus.

However, if you shoot weddings, events, or anything where subjects move quickly, the manual focus will hold you back. For travel photographers, the weight and lack of versatility make it a poor choice as a primary lens. In those cases, a lighter zoom or a native autofocus prime, even with a slower aperture, will serve you much better day-to-day.
