Resolution

Well, we were stunned by the results in this category and I reckon you will join us once you've had a look at the charts below. The Samyang produced nothing short of outstanding resolution figures for a lens in this class. The results are very even across the tested aperture range which means excellent to superb center resolution and very good to excellent borders and corners. Field curvature (flatness of the focus plane) is well controlled. The centering quality of the tested sample was well above average – a ""golden" sample in this respect

Lateral Chromatic Aberrations

The CA characteristic (color shadows at harsh contrast transitions) came as another surprise. Ultra-wide angle lenses often tend to be so-so here but the Samyang mastered this aspect … easily. The CAs are well below field-relevance at less than 0.3px at the image borders.
