Rokinon AS IF UMC 50mm F1.4

★★★★☆ 3.6 (130)

The Rokinon 50mm F1.4 for Nikon F mount pairs a bright f/1.4 aperture with 2 aspherical and 1 ED element plus Ultra Multi-Coating to reduce aberrations, and its weather-sealed body with 8-blade diaphragm yields smooth, durable bokeh. Manual focus only gives precise, deliberate control, and at just 536g it’s portable enough for extended handheld portrait sessions. This lens is best for portrait photographers using Nikon DSLRs who want a fast, budget-friendly prime with creamy background blur and tactile manual operation.

Resumen

The 30-Second Version

The Rokinon AF 50mm f/1.4 FE II finally adds fast, reliable autofocus to a lens that was already loved for its sharpness and value. It's still a strong autofocus performer in its class, but recent user sentiment has cooled a bit, landing at 78/100. For around $305, you get a weather-sealed, lightweight 50mm that handles most of what you'll throw at it, just don't expect universal praise.

Pros & Cons

Ventajas

  • Fast, quiet autofocus that rivals lenses costing much more. 76th
  • Lightweight 420g build with weather sealing for peace of mind.
  • Sharp center performance and excellent low-light ability.
  • Incredible value compared to Sony and Sigma 50mm f/1.4 alternatives.

Desventajas

  • Corner softness at f/1.4 can be distracting.
  • No built-in image stabilization.
  • Bokeh is just okay, lacking the creaminess of top-tier 50s.
  • Minimum focus distance of 40cm limits close-up versatility.

Opinión de los propietarios

The Word on the Street

3.6/5 (130 reviews)
👍 Owners consistently rave about its astrophotography and low-light performance, calling it a bargain for sharp, wide-aperture shots.
👎 A recurring complaint among users of the older manual version was the lack of autofocus, but this AF II model finally addresses that gripe entirely.
🤔 Corner sharpness at f/1.4 divides opinions, some find it perfectly usable while others consider it a trade-off for the budget price.

Performance

Autofocus is the headline act here. The Linear STM motor is quick and quiet, perfect for stills and casual video. In our benchmarks, it landed in the top tier, easily outperforming older screw-drive designs. Build quality is reassuringly solid without being heavy, a nice balance at this price. Where it stumbles is corner sharpness wide open, it's just not on par with lenses twice the price. And since there's no optical stabilization, you'll want steady hands or a body with IBIS for low-light handheld shots. Bokeh and macro scores are distinctly average, but for everyday shooting, the lens delivers where it counts.

vs Competition

Stack it against the Sony FE 50mm f/1.4 GM and the Sigma 50mm f/1.4 DG DN Art, and the Rokinon's value proposition becomes clear. The Sony is sharper edge to edge and has better bokeh, but it's also huge, heavy, and eye-wateringly expensive. The Sigma Art is a stellar performer but still costs a lot more and weighs a ton. For the average shooter, the Rokinon delivers 80% of that optical performance at a fraction of the price, with autofocus that doesn't feel like a compromise. If absolute image quality is your religion, go Sigma or Sony. If you want a great all-rounder that won't break the bank, this is it.

Precio

Value & Pricing

At its best price of around $305, this lens is a steal. For context, the Sony FE 50mm f/1.4 GM costs well over $1,300, and even the Sigma 50mm f/1.4 DG DN Art is usually double the Rokinon's price. You give up some corner sharpness and bokeh character, but you gain autofocus, weather sealing, and a much lighter bag. That's a trade-off most enthusiasts will happily make. Watch out for wild price swings across vendors, we've seen listings as high as absurd numbers, so stick to reputable retailers where it hovers in the sweet spot.

Overview

The Rokinon AF 50mm f/1.4 FE II is what happens when you take a wildly popular manual lens and inject a modern Linear STM autofocus system. It keeps the compact 420g body and tough weather-sealed build that owners loved, but now you get snappy, silent autofocus that ranks in the 87th percentile across our database. For Sony E-mount shooters eyeing a bright normal prime without selling a kidney, this thing is a serious contender.

Sharpness is solid in the center, but corners at f/1.4 are definitely softer, a trade-off you'll notice if you're a pixel-peeping landscape shooter. Still, the optical formula, with its 2 aspherical and 1 ED element, holds up well for portraits and walkaround photography. And with a 9-blade diaphragm, you get decent subject separation, though bokeh lovers may find it a touch clinical compared to pricier glass.

Common Questions

Q: Is this lens autofocus or manual focus?

This AF II version uses a Linear STM motor for fast, quiet autofocus. Confusion comes from the older manual-only Rokinon 50mm lenses, but this one locks on without any manual focus drama.

Q: Will it work on my Sony APS-C camera?

Yes, it's a full-frame E-mount lens that works perfectly on APS-C bodies like the a6000 series, giving you a 75mm equivalent field of view that's great for portraits.

Q: Does it have weather sealing?

Absolutely. The FE II version includes weather sealing, which is a real upgrade over the original and a nice perk for outdoor shooting in less-than-ideal conditions.

Who Should Skip This

Skip this lens if you demand tack-sharp corners at f/1.4 or rely on image stabilization for handheld video. For videographers, the lack of a de-clicked aperture ring and OIS makes it less ideal than Sony's own stabilized options. And if you're a bokeh purist who swoons over buttery background blur, save up for the Sigma 50mm f/1.4 Art instead. Recent user sentiment has also dipped to 78/100, so if you're the type who notices small optical quirks or build inconsistencies over time, this lens may frustrate you more than it delights.

Verdict

The Rokinon AF 50mm f/1.4 FE II is still a solid 50mm for many Sony E-mount owners, but the honeymoon phase is over. It fixes the manual focus headache of the original, keeps the sharp optics and solid build, and does it at a price that's hard to beat. Portrait photographers, walk-around shooters, and anyone needing a fast prime for low light will be happy. But with user sentiment slipping to 78/100, it's clear some owners are finding flaws after extended use. Hardcore landscape pixel-peepers, bokeh connoisseurs, and now a growing group of nitpicky everyday shooters may want to look elsewhere.
