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!

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.

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.

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.

Just about as good as my Zeiss Batis 18mm lens!
This review could have gone the other way last week. I received this lens from somewhere else...it was in mint condition, however, it was blurred in the corners even when shot at f8 or f9. Because of this I sent it back. The beginning of this week decided to get it again from somewhere else, marked "like new." I was blown away...very little distortion...corners were good, and good saturation. It was like a different lens from the week before. So there must be copy variation. I actually liked it good enough that I sent my Batis 18mm packing and sold it, and bought a second lens. Honestly, I see very little different between this Samyang and my Zeiss Batis. The Batis might be slightly better (but that could be easily debated), but not at 4 times the cost. Plus, most of my landscapes, portraits and event photography, I use high quality lenses. I just wanted a more wide angle lens for those rare occasions. I usually don't shoot wider than 24mm anyway, so this suits my purpose fine. Plus with landscape photography I use anything from 24mm to 400mm, and stitch images together when I want a much larger print. I got this Samyang used for about 180 dollars, but money well spent. I think the only reason a good copy of the Samyang matches well with the Batis is because the Batis is an older model now. If they had both been newer, updated versions, I suspect the Batis would have won by a landslide. This is the same reason I like The Sony 50mm f2.5 g lens over my old Sony 55mm lens.

Good Lens Performance, but Firmware Update Costs Extra
I like the lens performance. However, you have to spend an extra $50 to buy their specific lens station just to update the firmware. Why not just include a USB port on the lens itself? 4 stars for performance, minus 1 star for this inconvenient design choice.

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

Small, inexpensive and sharp!
The problem with the idea that mirrorless full-frame cameras are not much bigger than a micro four thirds camera is that the lenses are so much bigger. Frequently, the big g Master lenses are heavy and expensive. This Samyang is not. Put this on the front of a Sony mirrorless camera and you have a tremendous amount of power for not much weight.
