Colour fringing

There’s not much to worry about when it comes to colour fringing

all the lenses tested do an excellent job of minimizing colour fringing (or lateral chromatic aberrations) around highcontrast transitions within images, even towards the extreme edges of the frame. At medium to narrow apertures, the 85mm lenses tend to fare better than the 40mm and 50mm lenses, and the Sigma 85mm delivers the best performance of all for absence of fringing.

Lower values represent less fringing, and therefore better performance
