I have a ~30mm design I drew up in dbOptic thats f/0.25
I'd like sometthing wide and sharp and also a tele and sharp made with negative diffraction optical materials (already been used in visible wavelengths years ago to image well beyond the diffraction limit), basically.. limitless stopping down to reduce abberrations and only ever improve resolution.. no diffraction limit.
