I have just acquired a Samyang 14 mm f/28 ED AS IF UMC Lens at $350 !

This is a Korean made lens for full frame (and cropped) sensor DSLR cameras and has performance ratings better than

Canon EF 14mm f/2.8L II USM Lens which is a very fine lens but costs $2500 !

and here
versus Canon 14mm f2.8

This Korean lens is also sold under the Rokinon brand name, it has no autofocus and must be manually stopped down, but that’s no problems as the optical quality is really excellent. It has amazing resolution and extremely low chromatic aberration. You do not have to correct for CA.

If you have been delaying a purchase of a wide rectilinear lens because if the cost, contact Barney to view the lens and images from it.
