Samyang SYIO85AF-N

This 85mm f/1.4 is a budget portrait monster if you win the quality control lottery. But with a wobbly mount and a mandatory dock for firmware updates, you'll spend as much time troubleshooting as shooting.

The Samyang AF 85mm f/1.4 F for Nikon F is the poster child for 'you get what you pay for, but maybe less.' On paper it's a screaming deal: a fast portrait prime with weather sealing and a 95th-percentile AF motor for a couple hundred bucks. In reality, you're rolling the dice on a wobbly mount, a flimsy hood, and a mandatory dock you need to buy separately just to update firmware. If your copy is solid, you'll get gorgeous bokeh and sharp-enough images that make your portraits pop. If you get a dud, you'll be back to shooting with your kit lens while you wrestle with customer support.

The autofocus is genuinely snappy. Samyang's Ultrasonic Dual Linear motor punches way above its price class, keeping up with lenses costing three times as much. But here's the surprise: optical quality is dead average, landing at the 55th percentile. Sharpness is good wide open but never reaches the clinical bite of a Nikon gold ring. The bigger surprise is the real-world plague of build oddities. Our user sentiment data shows more complaints about a wobbly lens mount and a focus ring that can feel defective right out of the box than you'd expect from a 4.5-star rated lens. So yes, the AF is fast, but only after you've verified your copy isn't, you know, broken.

Prices across vendors span a laughable $239 to $107,114 (someone's clearly trolling). The real deal is the $239 listing—at that price, this lens is an absolute steal if you can stomach the QC lottery. Compare that to the Nikon AF-S 85mm f/1.4G at $1,500, and the Samyang becomes a tempting, if risky, shortcut to shallow depth-of-field portraits. Just don't pay over $300; above that, the risk outweighs the reward.

The listed competitors are mostly weird matchups: the Nikon Z 18-140mm and Canon RF-S 18-150mm are superzooms that can't touch the subject isolation of an 85mm f/1.4. The Viltrox 56mm f/1.7 is a clever APS-C alternative that delivers similar portrait framing for even less cash, but it's not full-frame. The Meike 50mm f/1.8 is fully manual focus, so if you need AF, this Samyang wins by default. Realistically, the Samyang's true rival is the used Nikon 85mm f/1.8G, which lacks f/1.4 but is built far better and never needs a dock for updates. If reliability matters more than one extra stop of light, go with the Nikon.

If you're a working photographer who can't risk missed focus during a paid shoot, skip this. The occasional copy has a mind of its own, and the last thing you need is a lens deciding to act up mid-session. Grab a used Nikon 85mm f/1.8G or a Tamron 85mm f/1.8 VC instead—they'll save your sanity.

Buy the Samyang AF 85mm f/1.4 F only if you're a budget-conscious portrait shooter who's willing to gamble. The lens can produce stunning images when everything works, but the documented mount wobble, flimsy hood, and mandatory dock make ownership feel like a part-time job. For everyone else, spend a bit more on a used Nikon 85mm f/1.8G or the Tamron 85mm f/1.8 VC and leave the troubleshooting behind.
