Personnellement j'en vois aucun ???, mais www.slrgear.com a l'air d'y croire. Je cite:
Chromatic Aberration
Despite the fact that the lens is quite long in the tooth, its multi-coating does a good job of reducing chromatic aberration - when the lens is stopped down to at least ƒ/4. There is some significant fringing in areas of high contrast at ƒ/1.8 or ƒ/2.8, which is fairly evident in our sample photos.
(au fait: "long in the tooth"=vieux)
Il s'agit du test du Olympus 50mm f/1.8

Excusez ma faute de frappe. C'est un aberration!
Non il n'y a aucun rapport.
Oui, ce n'est pas un aberration, c'est un énormité!
