Samyang 14 mm f/2.8 ED AS IF UMC

5. Chromatic aberration

We know already that the new lens’s resolution, compared to the older device, has been definitely improved on. The manufacturer also promised that such an increase wouldn’t influence the chromatic aberration result. Unfortunately they didn’t keep their word as you see on the graph below.

Samyang 14 mm f/2.8 ED AS IF UMC - Chromatic aberration

In the older version the chromatic aberration ranged from 0.04% to 0.06% on full frame. What’s more, it increased slightly on stopping down. In the new version of the lens the situation is the other way round. The aberration decreases on stopping down, reaching from 0.13% to 0.10% on small sensor and from less than 0.08% to 0.06% on a big sensor. At no point does it cross the medium level border so it can’t be called bothersome. The result is still good, taking into account the fact that the Nikkor 14-24 mm f/2.8 at 14 mm fared a bit worse than the new Samyang.
