I wasn't all that happy the first time of 2 that I tried my reverse adapter, for closeup photography.
However I seem to be getting the hang of it now
this blue flower is about the size of a plastic pin head.
Imagine my surprise to see another flower shape growing inside
here's a cropped version.
I used a Super Tak 35mm f2.0, of course reversed for both pic's
f16, for maximum dof, and hand held.
I think that I need a macro slider some day
