Hi Lou I don't have this problem! I illuminate with 4 flash units (YONGNUO YN560 III). The output is reduced to 1/128, 1/64 or 1/32. In the flash units, the diffuser is folded down. Around the object is one or two white plastic drinking cups. Distance flash unit to white plastic drinking cup approx....

Hello John, thank you

I am also surprised how good the NIKON M Plan, 60 / 0.7 ELWD, 210/0 is on the full frame,
with 200mm tube length and only 17% trim.

The steps are measured very unevenly and sometimes they go back. Since I work for photography on the repro stand and not on the microscope, I have tremors.
