As you can notice glancing at the chart above, the Nikkor performs the worst here. A slight improvement of results of the Sigma still didn’t allow it to catch up with the Sony. The Pentax remains outside the reach here – as its optical construction is an optimized version of a full frame lens it can correct many off-axis aberrations better than its rivals.
