The ultra macro gives very original results but it is clear that the goal is unusable for anything above the size of a 5 cent coin. Natural light photography is also difficult because of gluttony light macro lens and a flash (rather than twin flash ring) is often essential, another challenge to overcome given the working distance.
In summary, magnificent goal for the experts but with very limited applications (out of the lot!) And difficult job. This will require to be patient before you get your first good shots.
