The Canon EF 14mm f/2.8L USM Lens is reasonably sharp in the center wide open, but shows great improvement when stopped down to f/4 or narrower. The wide open corners do not have good sharpness even on a 1.3x FOVRC body. Full frame corners are soft wide open and begin looking decent at f/8, but the corners never catch the center-of-the-lens performance.
