  • Great value for money
Bought this lens primarily for astrophotography. After trying it out in Death Valley National Park in Feb this year, I am quite impressed by its performance. Daytime landscape shots are pretty sharp as well. Pros: 1) Extremely lightweight. It replaces my existing Astro lens Rokinon 14mm 2.8 + Sigma MC-11 which is around 700gms. This lens is feather light 2) Autofocus is quick and accurate 3) Distortion is low for a wide angle performance 4) Coma is well controlled Cons: 1) Build quality is okay, lens hood feels really cheap 2) Flare control is just okay 3) No manual focus markings as it is focus by wire. This can be an issue for astrophotography for some. I have found focusing around 80-100 ft at f2.8 gives decent clarity to both subject and stara Overall, for the price, it’s a great lens for someone who takes astro photos as a hobby. For more serious photographers, Laowa and Zeiss lenses will work better Highly recommended! ... show more

  • Great value, very light and small
For the price you pay, this is a great little lens. I bought it specifically for backpacking and peakbagging when I want a wide angle lens, but prefer to save a little weight. I usually have my 24-105 mounted on my camera, but there are times when I want to go a little wider, or a little faster (astro) so this lens fits the bill and saves me nearly a pound vs. bringing my 16-35GM. I find the picture quality to be great, but there are definitely some shortcomings but I'm not going to get into that. If you are a hard core pixel peeper or a professional you'll probably want something better. If you're looking to save some money and save some weight and size on a wide angle lens, you'd be hard pressed to find a better value for the money. I don't think you can find anything smaller or lighter either. Great little lens I'm happy with it. ... show more

  • Great value for money
This lens represents a good value for money, although it makes a lot of compromises. It’s not weather sealed, and feels very plasticky. However, this allows it to be very small and lightweight. Image quality is very good, out-resolving my a7 III at apertures at or above f4. IQ at f/2.8 is very sharp in the center, but some slight field curvature means the corners won’t ace flat test charts or the “brick wall” test (though for most uses, it’ll be nice and sharp). I personally prefer field curvature for landscape because equidistant objects will all be sharp. Distortion is low. Vignetting is moderate, and doesn’t really go away (probably due to the small size). Chromatic aberrations are well controlled, but not perfect (not ideal for astro). Autofocus is quick, accurate, but makes some light clicking noises. TL;DR: Great value and sharp. Excellent for hobbyists/enthusiasts. For pros: Buy it for travel, landscapes, vlogging, even architecture. Don’t buy for brick walls, flat spreads, or durability. ... show more

  • Great quality for tight budgets
As an owner of a Tamron 28-75mm, I wanted a wider lens for situations in which 28mm isn't enough, specially indoors. I had Tamron 17-28mm 2.8 and Sony 16-35mm 4.0, as main options, but they were in 800$ range and my main purpose with that lens was to cover specific moments, so I looked around some other. 18mm is a nice distance to work with, great in low light as it's 2.8. Not worried about stabilization as I often use it in a gimbal. The quality of pictures is awesome. It blends nicely with my Tamron and autofocus is a plus. For around 300$, it's a beast. ... show more

  • Fantastic lightweight ultra-wide angle lens for Sony FE!
Update 10/23/2019 So I got another copy of this lens, and it turned out it is way sharper at F2.8, especially in the center. Much happier with the new copy, so I give it 5 stars now. *********** This lens is so lightweight that my Sony A7RII tilts backwards! At F2.8, it is rather soft, and corners are even softer. But stop it down to F4.0, and the center gets very sharp! The corners get sharp at F8.0 or F11.0. I didn't see any issues with chromatic aberrations, in my short test. I even compared this tiny Samyang to the rather hefty Zeiss 16-35mm F4.0, and I was gladly surprised that at F4.0 and above, the Samyang matches Zeiss's sharpness in the center, while the Zeiss has some advantage in the corners between F4.0 and F5.6. But after F8.0, you would be hard-pressed to find a difference between the two. My two cents: Treat this lens as an 18mm F4.0, and you will be delighted. But for the price and **weight**, this lens is amazing! ... show more

  • Updated Review
UPDATED REVIEW: Finally got a good one. I guess I got 2 bad copies previously. This one is a keeper. Excellent center sharpness and decent edge sharpness. Good lens for the $. Lens hood is finicky however. Original review: I tried 2 of these...First was an open box from Amazon Whse. Lousy resolution particularly at the edges. Second was brand new but my cameras (A7 ii, a6400) couldn't recognize it. It was as if there was no lens on the camera. No AF, no anything. Couldn't take an image. Returned both. 2 strikes & "yer out!" Maybe you will have better luck. I have the Samyang 12mm AF for my a6400 and it's a champ. The 18mm FF not so much. ... show more

  • Promising, but NOT sharp
I’ve heard a lot of Samyang recently as I’ve been searching for a cheaper new lens for my Sony A7ii but I don’t have a lot of experience with the brand. My initial findings are that: It fits straight into the camera, no juggling or problems here. It is much lighter than I anticipated and keeps the camera nice and well balanced AUTOFOCUS WORKS - it’s not blindingly fast but it’s quiet and fairly accurate if not a little soft. Definitely not as good as Sony/Tamron or the likes Vignette is usable but only from F4 upwards, it’s very noticeable at F2.8 and up then only just disappears around F7. The lens is fairly sharp in the center and does get soft towards the outside edges, again it seems to be F5.6 upwards where this starts to even out I’ve used it only for around half a day so far but will continue to over the next week. Honestly, if it doesn’t improve much then it’s getting sent back in favor of the Tamron or Sigma ... show more
