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.
Very good for money, only budget ultrawide on FF, recomended.

Summary: Original Nikon FF ultrawide 14mm 2.8 cost 1400$, this lens - about 325$. Most disadvantage is lack of AF, and some distorsion (can be fixed by software). AF not so critical on wide lenses but it most weak part of this rokinor/samyang/prooptic.
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: 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!
