Rokinon Cine DS14M-MFT 14mm

A manual-focus cine lens that's great for video but useless for autofocus shooters. Only buy it if you're pulling focus by hand.

Optically, it's a standout. Our database puts it in the 64th percentile for optical quality, which is well above average for a wide-angle prime. The 7-element design with 2 aspherical and 2 ED elements keeps distortion and chromatic aberration in check, and the 9-blade diaphragm gives you decent bokeh for a 14mm (though that's not really the point). The macro score is surprisingly strong at the 76th percentile, but that's likely because the minimum focus distance of 254mm lets you get closer than most ultrawides. Build quality is middle of the pack, and the lack of stabilization shows in the 37th percentile. The long focus throw is a joy for precise manual focusing, but the f/3.1 max aperture is slow, and you'll be cranking ISO in low light.

The Viltrox Air AF 14mm f/4.0 is the obvious rival. It's cheaper, has autofocus, and is weather-sealed, but it's not a cine lens, so no gears and a shorter focus throw. If you need autofocus, get the Viltrox. If you're doing video and want manual control, the Rokinon wins. The Sigma Contemporary 18-50mm f/2.8 is a zoom with autofocus and a faster aperture, but it's not as wide and lacks the cine features. For pure video work, the Rokinon's unified gears and long throw make it a better choice than any of the kit zooms like the Nikon or Sony 16-50s, which are slow and plasticky.

The price range across vendors is a wild $200 to $5063, which tells you this lens is all over the map. If you can snag it for under $400, it's a solid deal for a cine lens with this build and optics. But if you're paying anywhere near the top of that range, you're getting ripped off. For the money, it's worth it only if you're already invested in the Cine DS system and need a wide-angle option. Otherwise, you can get a modern autofocus lens for less.

The Rokinon Cine DS 14mm f/3.1 is a weird little beast. It's a manual focus, ultra-wide prime built specifically for video work on Micro Four Thirds cameras. No autofocus, no stabilization, no weather sealing. Just a solid chunk of metal with gears and a 200-degree focus throw. If you're a run-and-gun shooter or a hybrid stills/video person, this thing will frustrate you. But if you're a dedicated video shooter who loves pulling focus by hand, it's a genuinely capable tool that won't break the bank. The one thing to know: this is a cine lens first, a camera lens second. Buy it for the gears, not for the convenience.

If you're looking for a versatile, autofocus wide-angle lens for everyday shooting, this isn't it. Go get the Sigma 18-50mm f/2.8 or the Viltrox 14mm f/4. And if you're a vlogger who needs stabilization, skip this entirely. The lack of IS and manual focus will make your footage look shaky and out of focus. This lens is for one type of shooter only: the dedicated video person who loves the tactile feel of pulling focus.

Buy this lens if you're a video shooter who wants a dedicated wide-angle cine prime for MFT and you're comfortable with manual focus. It's a niche tool, but it does its job well. If you're a stills photographer or need autofocus, skip it. The optics are good, but the lack of modern features makes it a hard sell for anyone not already committed to the cine workflow.
