Samyang Samyang 12mm f/2.0 AF Lens for FUJIFILM X Review
The Samyang 12mm f/2.0 AF is a specialist's dream: incredibly sharp, built like a tank, and surprisingly affordable. Just don't expect lightning-fast autofocus.
The 30-Second Version
A hidden gem for specialists. You get pro-level optics and weather sealing for under $400, but the autofocus is just okay. If you shoot static wide-angle scenes, it's a no-brainer.
Overview
This Samyang 12mm f/2.0 is a weird one. It's a fantastic piece of glass that feels like it was built in a lab for photographers who hate compromises, but then they forgot to tell anyone about it. The one thing to know? You're getting pro-grade optics and weather sealing in a tiny, 213g package for a price that should make Fuji and Sony blush. It's a specialist's tool, not a walk-around lens, and it absolutely nails the job it was designed for.
Performance
The optical performance is the star here, landing in the 87th percentile. That means it's sharp, even wide open at f/2, with minimal distortion for such a wide angle. The build quality is even more impressive, sitting in the 97th percentile. It feels like a tank. The surprise, and it's not a good one, is the autofocus. It's fine in good light, but our database shows it's slower and noisier than most modern lenses, ranking in the bottom half. For static landscapes or architecture, it's fine. For anything moving, you'll need to be patient.
Pros & Cons
Pros
- Insanely good build and weather sealing for the price. 97th
- Extremely sharp optics, especially for an ultra-wide. 87th
- Tiny and lightweight, perfect for travel kits. 75th
- Fast f/2 aperture is great for astrophotography or low light. 68th
Cons
- Autofocus is merely okay, and it hunts in low light. 7th

- It's a prime, so you have to love the 18mm equivalent field of view.
- Almost no one talks about it, so finding user tips is hard.

Value & Pricing
At $280, this lens is a steal. At $399, it's still a very good deal, but you should shop around. The optical and build quality punch way above that price tag. Just know you're paying for glass and metal, not for the snappiest autofocus system on the block.
Price History
vs Competition
The most direct competitor is the Fujifilm XF 14mm f/2.8 R. It's sharper in the corners and has Fuji's legendary build, but it's slower (f/2.8), more expensive, and lacks weather sealing. For versatility, the Tamron 17-70mm f/2.8 is a zoom that covers this focal length and more, with stabilization, but it's bigger, heavier, and not as sharp at 12mm. If you need autofocus speed above all else, stick with your kit lens. If you want optical purity and durability in an ultra-wide, this Samyang is the move.

Common Questions
Q: Is the autofocus really that bad?
It's not bad, it's just average. For still subjects, it's perfectly accurate. For video or moving subjects, it can hunt a bit and the motor isn't silent. If you need speed, look elsewhere.
Q: How's the distortion? It's a 12mm after all.
Surprisingly well-controlled for an ultra-wide. There's some barrel distortion, but it's easily corrected in software. The straight lines stay pretty straight, which is great for architecture.
Q: Is the weather sealing actually good?
Yes. The build is in the 97th percentile for a reason. It has a gasket at the mount and tight seals. We'd trust it in a light rain or dusty environment without a second thought.
Who Should Skip This
If you're looking for a do-everything walk-around lens or need blisteringly fast autofocus for sports or kids, this isn't it. Go get the Tamron 17-70mm f/2.8 zoom instead for that versatility.
Verdict
We're recommending this lens, but with a very specific audience in mind. If you shoot landscapes, real estate, interiors, or the night sky with a Sony or Fuji APS-C camera, and you value image quality and build over lightning-fast focus, buy it. It's a tool that does one job exceptionally well. For everyone else, there are more versatile options.
