Do not expect less purple fringing from the 85/1.8 on a full frame. If you didn't like it on your crop body, you won't like it on your full frame either. Itīs not less because the FOV is greater on the full frame, au contraire.... Both 85 have their chromatic abberrations, but they are quite different in character. The 1.8 shows quite some highlight purple fringing, while the 85L shows more longitudinal CA with a cyan and magenta cast diffracting in the front and back of the focus zone.
No lens is without residual abberrations. But some suffer less than others. Without any doubt macro lenses around 100mm have the best suppression of all kind of abberrations. The conversion from 3D reality to 2D sensor however is less convincing to my taste.
Another `issue` I see in a setup with the 24-105 is that the 100L doesnīt bring a lot extra, but one stop opening speed, a little better IS system and of course better close focus capabilities. In my bag with a 24-105/4.0L IS a faster portrait lens would better fit the bill, unless I was really interested in macro too.
