Summary: I have a Nikon D7000 and I've been lacking (and missing) a wide-angle lens ever since I purchased it nearly two years ago. If you are like me, you've been looking for one for a long time, but are rather overwhelmed by SO many different choices and the huge difference in cost.
Surprisingly sharp, and only minimally flawed. Great value.

Summary: This review is for the Rokinon branded 14mm f/2.8 ED AS IF UMC for Nikon AE (auto exposure) with the focus confirm chip. As tested on my Nikon D600 (a full frame "FX" body) == Build Quality & Cosmetics == Mine has a red band by the aperture wheel rather than a gold band near the front.
Summary: NOT AUTO-FOCUS, but great other-wise. Bought this lens for my Nikon D600 and I thought I read enough on it to understand everything I needed. I however misunderstood when it said it had a "chip" for Nikon cameras.
Summary: This lens is about the best thing I have for my full frame DSLR's. On my crop frame cameras it is still a great wide angle and perfect for real estate which I use it almost every day. On a full frame it is 10 times better because of the larger sensor.
Summary: I could not be happier with this lens. I downloaded adobe's lens profile for it (Nikon D700 samyang 14mm f11) and the complex distortion is a thing of the past. This profile works pretty well with most full frame cameras. A friend of mine uses it with his 5DMk3.
Summary: This is a great lens if you like to shoot manual. its a great rival to the Tokina 11-16mm, but obviously falls short of that lens in many features. but that lens will only cover full frame at 16mm. I put this lens on my 35mm camera and love the image. A great deal!
