Samyang 14mm f/2.8 ED AS IF UMC Sample A @ f/2.8, by Dean Chiang, Xyclopx

Samyang 14mm f/2.8 ED AS IF UMC Sample B @ f/2.8

This is the Rokinon (Samyang) 14mm f/2.8 ED AS IF UMC shot at f/2.8, crop of the upper right corner. This copy is very badly decentered on the whole right side of the frame. Even center sharpness is very bad. Left side is okay.
