>>3411165I'm not at home and cannot post field examples, but I started out doing macro with some Olympus, an inverted 50mm and a flash. Results were good, but it was a sketchy setup. At home I usually remove the microscope head from the stand, hang in my camera and take shots with an inverted zoom and two triggered flashes. In both setups, focus is mainly achieved due to subject distance. Earlier, I used a Nikon 995 that was attached to one of the oculars, but quality was really bad sometimes.
Check some of the various forums and fb groups.
Here's an example through the Leica S6 with automatic stacking.
