Here are two images taken with a 90mm f2 macro and a 80mm f4 macro -
the later auto version.

Some droplets evaporated between shots and the lighting changed a bit
due to cloud movement. Each lens was set to f5.6 and for a 1:2
reproduction ratio, or as near as I could manage.
The top image was taken with the 90/2. To the right are magnified
sections of the right hand portion of the original images for the
resolution conscious.
The images were scanned from negs using a Polaroid SS4000
I think one can clearly see that there is a difference in the bokeh
of each image - the 90/2 macro has a 9 blade diaphragm while the 80/4
has 6 blades.
