Interesting comparison of the AFS 58mm vs 60mm micro. In the flower picture, the background bokeh appear similar for both lenses - in "quantity" and smoothness. The picture taken with the 60mm shows stronger green outlining on the white object in the background, which suggests longitudinal CA is less well controlled - the 58mm is better. In the picture of the seeds, the 60mm shot again shows more of a greenish tinge in the shadows between the seeds. In this case the 60mm shot appears to have less DOF - the background seeds are more out of focus than the 58mm shot, hard to say why.
