Offering an ultra-wide field of view, the Sony E-mount AF 18mm f/2.8 FE from Rokinon is also distinguished by its especially compact and lightweight design. The rectilinear wide-angle design is well-suited for landscape, architecture, and interior subjects, as well as being suitable for astrophotography applications. Its optical design includes a series of aspherical, high refractive index, and extra-low dispersion elements, which reduce a variety of aberrations in order to produce well-controlled, sharp, and clear imagery. An Ultra Multi-Coating has also been applied to individual elements to suppress flare and ghosting for improved contrast and color accuracy. Additionally, the lens's linear STM autofocus motor works in conjunction with Sony cameras' AF systems for quick, quiet, and precise focusing performance, and manual focus override is also available for more refined control.

Rokinon AF 18mm f/2.8 Reviews
Great for being only an AF lens
If you are always going to shoot with AF, then this lens is just fine. I sometimes like to override and shoot manual in low light, however, the photos I have taken with this lens I am happy with, especially for the price point.
This lens is incredibly light and takes very descent stills. That said, when shooting video outside in the sun on my a73, I get constant light-dark flickering that makes the video unusable. I'm not sure what's going on, but it seems like the camera/lens can't decide on an exposure so it switches back and forth multiples times a second. This does not happen with any of my Sony lenses. It's possible that I received a bad copy or perhaps this just is not supposed to be used for video.
Super impressed with this lens
I was looking for a cheap frame with a wide angle that would give me the opportunity to take group pictures and landscapes. I just used this lens for a kid's birthday party and it worked really well. I was so impressed. It's so compact and lightweight. If you are a new photographer on the rise (like me) and need a cheaper option for a frame like this please buy it, I guarantee you would love it.
Great little lens
Nice lens for the price.
Good enough for the money
Purchased for use with a Sony 6600 in otder to achieve an almost 28mm effect for use in practicing street photography. At close range it really good. Focus is quick and accurate. At about 20' away things start to go soft. It's not a champion of low light, but does well in open shade. Four stars = it was pretty much what I expected. All in all, not a bad lens. Certainly good enough to learn street photography on.
Good enough for what I do
I bought this to use it for videos with my Sony a6000 and also for wide angle for my a7lll when I shoot landscape. I shoot videos in manual focus so not a big deal but it's AF is noisy. Also when I focus manually, focus is noisy. I don't record audio for my videos so even if I shoot with AF it's not a problem at all. But I can't use it for any vids that record audio because if it. But good enough lens for what I use it for.
Light weight and sharp with sony a7iii
A very good travelling Len to go. Fairly sharp at F6.3 and good colour rendering. With the lens profile in lightroom, it is fine for architecture photography. good deal in such price.
The best vlog lens. Significantly improved with firmware.
I used this lens a couple years ago originally when it was first released, but decided to not keep it because it was noisy for video focus and had some weird aperture behavior in certain conditions. Since then the lens has had no less than 5 firmware updates since it was first released and I can say that the upgrading from the version 1 firmware to the the latest firmware from Samyang (Version 6 as of Jan 2022) has dramatically improved the AF performance of the 18mm/2.8, particularly with continuous AF, Eye-AF and face detection and especially with video noise. Now, it performs exactly like a native Sony lens as far as I can tell. AF-C in video is silent, ultra accurate, works with tracking/face detection/eye-AF and is fast when I need it to be. Note, however, that in order to update the firmware, you need to use the Rokinon/Samyang Lens Station and Lens Manager software in order to be able to upload the new firmware to the lens. This lens shines as the absolute best choice for vlogging on a Sony full-frame camera. Its field of view is perfect for handheld selfie video (great with the Sony GP-VPT2BT vlogging handle). It's wide enough that you can use just your forearm and your elbow can comfortably sit against your body for extra support and still get a nice shoulder/head framing. It's also light enough that extended arm's length shots are doable without too much strain, especially when mounted to the a7C body. It's also possible to use APS-C mode and ClearImage Zoom when recording video to effectively turn the lens into effectively an 18-40mm zoom while retaining 4K output resolution. For stills, the lens is also excellent. It has fairly dramatic light fall off at f/2.8, but that improves somewhat stopped down (typical for a wide angle anyway). It's nearly as sharp as my $1500 Zeiss Batis 18mm f/2.8 at f/2.8 and matches it by f/4. It also has minimal coma at f/2.8, so it's a great budget option for landscape astrophotography and nightscapes. My Zeiss Batis 18mm is probably going to go up for sale because of this lens. For the price, the weight and the performance of this lens (especially when updated with the latest firmware), the Rokinon/Samyang 18mm f/2.8 is an excellent budget choice.
