Rokinon AF IO3518-E 35mm
Its bright f/1.8 aperture, two aspherical and two ED elements ensure sharp, controlled images, while the linear STM motor delivers fast, quiet autofocus on full-frame Sony E-mount bodies. The lens weighs just 210g and features a customizable focus ring switch that allows intuitive on-the-fly exposure adjustments. Best for portrait and street photographers needing a lightweight, high-quality 35mm prime with dependable autofocus.

The 30-Second Version
The Rokinon 35mm f/1.8 is a dirt-cheap, featherlight prime that nails bokeh and low-light shooting for Sony full-frame. At $279, it's a no-brainer for portrait and street work, but skip it if you need stabilization or weather sealing.

The proof
Performance
Our database shows the Rokinon's best tricks are its bokeh (89th percentile) and aperture brightness (87th), which combine for creamy backgrounds and solid low-light performance. Build quality lands at the 82nd percentile, which matches the feel in hand, dense and well-assembled for a plastic-heavy design. Optical sharpness is middle-of-the-pack at 69th, meaning it's good but not stellar; center sharpness is fine wide open, but corners soften up a bit. Autofocus is average in speed (54th percentile), quiet and accurate for stills but not dependable for fast action. The real letdowns are versatility (35th) and the lack of stabilization (34th), which makes handheld video or slow shutter stills tricky on non-IBIS bodies.

vs Competition
Stacked against the Sony FE 35mm f/1.8, the Rokinon gives you near-identical optical flavor for half the money, but the Sony fights back with weather sealing and a linear AF motor that's snappier. The Sigma 35mm f/2 DG DN is another alternative, pricier but with a lovely aperture ring and all-metal build. If you're okay with a zoom, the Tamron 17-70mm f/2.8 covers this range and adds stabilization, but it's heavier and not a prime. The Rokinon carves out its niche as the affordable, lightweight option that still delivers where it counts.

Overview
The Rokinon AF 35mm f/1.8 FE is one of those lenses that just makes sense if you shoot Sony full-frame. At 210 grams, it's absurdly light, and the f/1.8 aperture gives you genuine low-light flexibility and subject separation. Our testing puts its bokeh in the top 11% of all lenses we've analyzed, which is impressive for a budget prime. Build quality is solid, far better than you'd expect at this price, but you don't get weather sealing or stabilization.
Common Questions
Q: Does this lens have image stabilization?
No, the Rokinon 35mm f/1.8 FE lacks optical stabilization, so you'll rely on your camera body's IBIS if it has one.
Q: Is it weather sealed?
It has no weather sealing, so you'll want to avoid using it in rain or dusty environments.
Q: How fast is the autofocus?
It's average. The linear STM motor is quiet and accurate for single shots, but it's not the quickest for tracking fast-moving subjects.
Who Should Skip This
If you need reliable weather sealing or image stabilization, this lens isn't for you. Landscape photographers should also look elsewhere; our tests put its landscape performance at a weak 45.3 out of 100, likely due to softer corners. And if you shoot fast action or sports, the average autofocus will leave you frustrated.
Verdict
Grab this lens if you're a portrait or street shooter on a Sony E-mount body who wants a lightweight, fast 35mm without spending a fortune. The bokeh alone makes it worth the price, and the build will surprise you. Just be realistic about the missing stabilization and weather sealing, and you'll have a lens that's easy to love.
