Lateral Chromatic AberrationDifferent wavelengths (colors) of light have different magnifications and produce colored halos around high contrast objects near the frame edges.
Distortion
The lens measures a very significant 2% barrel distortion (numeric average between all apertures). The following shows the coefficients and a sample test chart.
All data gathered using Imatest.
