Samyang Rokinon 12mm f/2.0 CS Lens for Sony E, Silver Review

The Rokinon 12mm f/2.0 is a manual focus ultra-wide prime lens for Sony APS-C cameras. It delivers sharp images and a bright f/2.0 aperture at a very affordable price, making it a top pick for astrophotography and landscapes. Just know you're giving up autofocus and stabilization for that performance.

Looking for a wide-angle prime lens for your Sony APS-C camera that won't break the bank? The Rokinon (also sold as Samyang) 12mm f/2.0 is a manual focus lens that's become a cult favorite, especially for astrophotography and landscapes. For around $250, you get an ultra-wide 12mm focal length (an 18mm full-frame equivalent), a bright f/2.0 aperture, and a surprisingly solid metal build. It's a simple, no-frills tool designed for photographers who want to control focus themselves and capture expansive scenes without spending a fortune.

This lens is built specifically for Sony E-mount cameras with APS-C sensors, like the a6000 series or the ZV-E10. If you're shooting on a full-frame Sony body, it'll force your camera into crop mode, which isn't ideal. But for the right user, its combination of speed, width, and sharpness punches well above its price tag. It's a classic case of a company cutting costs in the right places—you lose autofocus and stabilization, but you gain optical quality and a fast aperture for a very reasonable sum.

Our database shows this lens scores in the 79th percentile for optical performance, which is impressive for its price. In practice, that means it's sharp, especially when stopped down a bit from f/2.0. The f/2.0 aperture itself lands in the 69th percentile, making it noticeably faster than most kit zooms and a real asset for low-light shooting like astro or indoor events. The trade-off is in the features you don't get: it scores in the bottom half for autofocus (46th percentile, because it has none) and stabilization (36th percentile, also none). That's the deal. You're getting great image quality and speed, but you have to do the focusing work yourself.

At $249, the Rokinon 12mm f/2.0 is a steal if your needs align with its strengths. You're essentially paying for great glass and a fast aperture, and skipping the electronics. Compared to Sony's own 10-20mm f/4 PZ G lens, which costs over twice as much, you get a faster aperture but lose autofocus, power zoom, and stabilization. For astrophotographers or landscape shooters on a budget who don't mind manual focus, this lens offers performance that rivals lenses costing hundreds more. It's a fantastic second lens to pair with a standard zoom.

Let's name some names. If you need autofocus on a Sony APS-C camera, the Sigma 16mm f/1.4 DC DN is a popular alternative. It's a different focal length (less ultra-wide, more standard wide), but it's also fast, sharp, and has excellent AF. It's also more expensive. The Viltrox 13mm f/1.4 is another AF competitor that's wider and even faster, but again, you'll pay more. For a manual focus alternative, the Laowa 9mm f/2.8 Zero-D is wider and offers unique features like a bulbous front element for minimal distortion, but it's slower (f/2.8) and often pricier. The Rokinon's value proposition is clear: it's the most affordable path to a fast, ultra-wide prime for your Sony crop-sensor camera.

Skip this lens if you need autofocus. That means videographers who rely on continuous AF, event shooters capturing candid moments, or anyone who finds manual focus slow or intimidating. Also, if you shoot on a full-frame Sony body, this isn't the right tool—look for a lens designed for full-frame coverage. For those users, a lens like the Sigma 16mm f/1.4 DC DN (for APS-C AF) or a used Sony FE wide-angle (for full-frame) would be a better fit.

Should you buy the Rokinon 12mm f/2.0? If you shoot landscapes, real estate, interiors, or the night sky with a Sony APS-C camera and you're comfortable with manual focus, this is an easy yes. The image quality is fantastic for the money, and the f/2.0 aperture is a genuine benefit. But if you rely on autofocus for run-and-gun video, street photography, or capturing fast-moving subjects, you'll likely find the manual-only operation frustrating. It's a specialist's tool, not a generalist's. For the right photographer, it's one of the best value lenses you can buy.
