Fisheye on Macro?
Yes it works and you get some fisheye distortion. No serious vignetting (corner darkening) though. The images do not seem as as sharp as with the macro alone.
I'm not sure why you would want to do this though. You could probably get the effect you want better in post processing using Gimp or similar.
