I only link well known and reputable sellers. At 18mm, there is noticeable coma in all the stars of the 'cup', although the stars in the 'handle' are far enough away from the corner to be unaffected by coma. You can take the performance, usability, robustness and professional quality of L lenses for granted, but what's not always so obvious is the research, precision and passion that continues to drive L-series lens development. There is a lens for practically every need included here.
