Samyang 14mm F2.4 XP Premium Nikon AE

I believe you wont find a sharper and lighter wide angle prime for the full frame camera. The only thing I would like to see improved is lens flaring. Great effort from Samyang. They continue to push the limits of cheaper lenses.

I have used the Sigma 14mm and now this Samyang 14mm; it is extraordinary in quality. I know there have been some QC issues with Samyang (Rokinion), and if you have some blurring on edges, send it back for replacement...this one doesn't have issues and is extremely sharp when I tested it...it is prone to more vignetting than the Sigma 14, but the edges are sharper, as is the whole image...great buy for the price.
