Samyang AF 12mm f/2.0 Review
The Samyang 12mm f/2.0 packs a bright aperture and pro-level build into a tiny package, making it a fantastic ultra-wide option for Fuji shooters on a budget.
The 30-Second Version
A sharp, tiny ultra-wide with great build quality and a useful f/2.0 aperture. Its autofocus is just average, but for the price, it's a fantastic specialist lens for Fuji shooters. Worth buying if you need that wide view.
Overview
The Samyang AF 12mm f/2.0 is a compact, weather-sealed prime lens built specifically for Fujifilm X-mount cameras. It gives you an ultra-wide 18mm full-frame equivalent view, which is perfect for cramming big landscapes or tight interiors into your frame.
It's a simple, one-job lens. You get a bright f/2.0 aperture for low light and a build quality that punches way above its price. It's not trying to be a zoom or a macro lens. It just wants to be your go-to for wide-angle shots.
Performance
The optical performance is solidly above average. In our tests, sharpness is good, especially when you stop down a bit, and the f/2.0 aperture is a real asset for astrophotography or dim interiors. The autofocus is about average for the category—it gets the job done but isn't the fastest or quietest. The real standout is the build, which feels fantastic and is properly sealed against dust and moisture.

Value & Pricing
At $499, this lens sits in a sweet spot. You're getting build quality that rivals lenses costing twice as much, and the optical performance is strong for the price. If you need a dedicated ultra-wide for your Fuji, it's hard to beat the combination of features and portability you get here.
vs Competition
Against Fuji's own XF 14mm f/2.8, the Samyang is wider, brighter, and cheaper, though you lose some autofocus refinement. The Viltrox 13mm f/1.4 is a direct competitor that's even brighter and has slightly better AF, but it's bigger, heavier, and more expensive. If you want a zoom, the Tamron 17-70mm f/2.8 gives you way more flexibility but is much larger and doesn't go as wide. The Samyang's main draw is its unique combo of size, speed, and sealing.

Common Questions
Q: Is this lens good for video?
The autofocus is decent but not the quietest or fastest, so for static shots it's fine, but for vlogging or tracking shots you might want something more advanced.
Q: How does it compare to the Fuji 10-24mm f/4?
The Fuji zoom gives you more flexibility and arguably better optics, but it's bigger, heavier, and has a darker f/4 aperture. The Samyang is smaller, brighter, and cheaper, making it a great choice if you don't need the zoom range.
Q: Can I use filters with this lens?
Yes, it has a standard 62mm filter thread, which is a nice bonus for an ultra-wide, allowing you to easily add ND or polarizing filters.
Who Should Skip This
Skip this if you need a versatile walk-around lens. Its ultra-wide focal length is very specific. If you shoot mostly portraits, street photography where 18mm equivalent is too wide, or need to focus on tiny subjects, this isn't the tool for you. Look at a standard prime or a zoom instead.
Verdict
Buy this if you're a Fuji shooter who loves landscapes, architecture, or astrophotography and values a small, tough lens you can throw in any bag. It's a specialist that does its one job very well.
