EU price and availability
Samyang 50/1.4 FE is the first autofocus lens in over 40 years of Samyang’s class-leading core optics technologies.This launching expands the boundaries of Samyang Optics photo lens line-up from manual focus only, to now include autofocus lenses. The lens will be globally available from August, and the suggested retail price is EUR 579.
Centre sharpness is disappointing when shooting wide-open at f/1.4, acceptable at f/2, and very good from f/2.8 onwards, with f/16 being adversely affected by diffraction. The edges aren't quite as sharp as the centre, with f/5.6-f/11 producing the sharpest results.
AF mechanism is pretty noisy.

Review
Center sharpness is very good from the start. but edges are quite soft initially. Chromatic aberrations are very well controlled in the center of the frame.
AF is quiet in operation and locks on swiftly and reliably.
