Rokinon AF 24mm f/1.8

The Rokinon 24mm f/1.8 AF is a compact, weather-sealed wide-angle prime for Sony E-mount that delivers fast autofocus, a dedicated astrophotography mode, and full-frame coverage at a budget-friendly price. It's not the sharpest or the best for bokeh, but it's a fantastic value for street, travel, and night sky shooters. If you want a fast 24mm prime without spending Sony GM money, this is the one to get.

Sharpness is good but not class-leading. The optical score lands in the 73rd percentile, which translates to solid, dependable performance without any wow factor. The 11 elements in 8 groups, including 2 aspherical and 2 ED elements, do a decent job controlling aberrations and distortion. You'll see some softness in the corners wide open at f/1.8, but stop down to f/2.8 or f/4 and things tighten up nicely. The UMC Ultra Multi-Coating helps with flare and ghosting, which matters when you're shooting into streetlights or the sun.

Autofocus is where this lens surprises. The Linear STM motor is fast, quiet, and accurate, ranking in the 86th percentile in our database. For a third-party lens, that's genuinely impressive. It tracks moving subjects well on modern Sony bodies, and the focus hold button is a nice bonus for locking focus or assigning a custom function. The minimum focus distance of 190mm gives you a 1:4.7 magnification ratio, which isn't true macro but is close enough for detail shots and close-up work. Our macro score of 67.1 out of 100 reflects that. The 9-blade diaphragm produces decent bokeh, though it's not the creamiest we've seen. The bokeh score sits in the 24th percentile, so if you're buying this for dreamy background blur, you'll be underwhelmed. The lack of optical stabilization is a real gap, especially for handheld video work. The stabilization score is a mediocre 36th percentile, and on Sony bodies without IBIS, you'll need to keep your shutter speed up or use a tripod.

The most obvious competitor is the Sony 24mm f/1.4 GM. That lens is sharper, has better bokeh, and focuses even faster, but it's also significantly more expensive and heavier. If you're a professional who needs the absolute best image quality, the Sony is the better choice. But for hobbyists and enthusiasts, the Rokinon makes a strong case. The Sigma Contemporary 18-50mm f/2.8 DC DN is another option, but that's an APS-C zoom, so it doesn't cover full-frame sensors. It's more versatile in terms of focal length, but you lose the f/1.8 aperture and full-frame coverage. The Tamron Di III 17-70mm f/2.8 is similar, a versatile APS-C zoom with stabilization, but again, no full-frame support.

The Viltrox AF 35mm f/1.7 XF is a different beast entirely. It's a 35mm prime for Fujifilm X-mount, so it's not a direct competitor for Sony shooters, but it's worth mentioning because it's another budget-friendly fast prime. If you're on Sony and want a 24mm prime, the Rokinon is really competing against the Sony 24mm GM and maybe adapted lenses. The Panasonic Leica DG Vario-Elmarit H-ES12035 and Nikon NIKKOR Z DX 18-140mm f/3.5-6.3 VR are for different systems entirely, so they're not relevant for Sony E-mount users. The bottom line: if you want a fast 24mm prime for Sony full-frame without spending Sony GM money, the Rokinon is basically your only serious option.

Pricing is all over the place depending on where you shop. In the US, you'll find it between USD 359 and USD 449 across three listings, so it pays to shop around. The best deal we've seen is at the lower end of that range, so check multiple vendors before you buy. In Canada, the spread is even wider, from CAD 499 to CAD 663 across two listings. European buyers will pay around EUR 516 in Germany or GBP 416 in the UK. For a full-frame 24mm f/1.8 with weather sealing and solid autofocus, the US price is genuinely competitive. The Sony 24mm f/1.4 GM costs well over twice as much, and while it's sharper and has better bokeh, the Rokinon gets you 80% of the way there for a fraction of the cost. If you're on a budget and want a fast wide prime for Sony E-mount, this is one of the best values out there.

The Rokinon 24mm f/1.8 AF is a compact wide-angle prime for Sony E-mount, and it's one of those lenses that makes you wonder why you'd ever lug around a big zoom for everyday shooting. It covers full-frame sensors natively, so you get a true 24mm field of view on an A7 or A1, and a 36mm equivalent on APS-C bodies like the a6000 series. At 230g with a 58mm filter thread, it's genuinely tiny for what it offers. The f/1.8 max aperture is the headline spec here, and it's paired with weather sealing in five areas, a customizable focus hold button, and a dedicated astrophotography mode. That's a lot of features for a lens that often sells between USD 359 and USD 449 in the US.

People searching for a fast 24mm prime for Sony full-frame are usually trying to decide between this, Sony's own 24mm f/1.4 GM, and maybe a Sigma or Viltrox alternative. The Rokinon undercuts the Sony GM by a huge margin while still delivering solid optical performance. It's not going to win any sharpness contests against glass that costs three times as much, but for the price, it's a compelling little package. The build quality is a standout, ranking in the 90th percentile in our database, which is impressive for a budget-friendly prime.

Is the Rokinon 24mm f/1.8 good for astrophotography? Yes, and that's a big part of its appeal. The dedicated astro mode switches the lens to manual focus and lets you lock infinity focus with a confirmation light, which is a thoughtful touch for night sky shooters. The f/1.8 aperture pulls in a lot of light, and the 24mm focal length is wide enough for Milky Way shots without being so wide that everything looks tiny. It's not perfect, but it's a lot of capability for the money.

Skip this lens if you need optical stabilization for handheld video work, or if you're a portrait shooter who cares about creamy bokeh. The bokeh quality is mediocre, and the lack of stabilization is a real limitation on Sony bodies without IBIS. If you're a professional who needs the absolute best image quality and corner-to-corner sharpness wide open, the Sony 24mm f/1.4 GM is worth the extra money. And if you're on APS-C and want more versatility, a zoom like the Sigma 18-50mm f/2.8 or Tamron 17-70mm f/2.8 might serve you better, even though you'll lose the f/1.8 aperture and full-frame coverage.

Should you buy the Rokinon 24mm f/1.8 AF? If you're a Sony E-mount shooter who wants a fast, wide prime for astrophotography, street photography, or travel, and you don't want to spend over a grand, then yes, absolutely. This lens delivers solid sharpness, excellent autofocus, and a genuinely useful feature set in a package that weighs almost nothing. The astro mode alone is worth the price of admission for night sky shooters.

But if you need the best possible image quality, creamy bokeh, or optical stabilization, this isn't the lens for you. The lack of stabilization is a real limitation for handheld video, and the bokeh is nothing to write home about. The limited social proof, with only 9 reviews in our database, means you're taking a bit of a gamble on long-term reliability and firmware support. Still, for the price, it's hard to argue with what you get. This is a lens that punches well above its weight class.
