Just when I had finally talked myself into keeping my old 85mm f/1.8, this happened:
What we got here is not failure to communicate, but failure of the lens to focus different colors on the same plane. It’s called chromatic aberration, and it’s breaking my heart.
I can accept that the 85mm f/1.8 lacks an internal motor and a “D” chip for integrating distance information into exposure calculations. I can accept that it is noisy and a little temperamental about focusing. But I cannot accept that my primary portrait lens adds color fringing to the most important part of a portrait. Looks like I’ve got some homework to do.
