I love the feel, short DOF and the crispness of the lens, but I'm experiencing some really ugly chromatic aberration on a lot of wide open stuff. I'm using it on a D50. This shot was taken at F2 and around 1/320. Am I expecting too much from the lens on this body, or could I just have a bad copy? I'm experiencing some CA all the way up to F2.8. I can post more examples when I have access to my home comp later tonight.
