I agree. It's tempted me to have another try with the A* 200/2.8 and the 1.7x adapter. The first time I tried this combination on the *ist-D (during my first try-out with the camera, I believe) I was a little disappointed with the purple fringing around branches, and attributed this solely to CA from the optical components. Now I know a little more about these effects, and realise that perhaps there may have been other causes.
Seeing great shots like this from the AF adapter and a 200mm lens definitely makes me hope that I was too hasty in abandoning this. Perhaps I can get the local hummingbird population to cooperate ...
