lack of problems with longitudinal chromatic aberration,
low astigmatism,
moderate vignetting on the APS-C/DX sensor,
silent and quick autofocus,
5-year long warranty period.
Cons:
worse distortion correction than in the case of the rivals,
problems with autofocus accuracy,
huge vignetting on full frame,
impossible to use classic filters.
Samyang’s lineup currently features as many as three full frame 14 mm lenses: two manual ones, as fast as f/2.4 and f/2.8, and the autofocus model, tested here. To be honest all three perform similarly well, presenting a very good optical level. If you don’t need autofocus, and it is not obligatory with such angles of view, you can save money and buy the cheapest manual lens in this group, paying two times less than you’d need for the autofocus model. If you, however, decide to buy the Samyang AF 14 mm f/2.8 EF you won’t regret your decision either. The lens is able to provide good quality images without any traces of aberration and, what’s important, with good resolution across the frame in most of cases.
