>>4459675>How do I get into microphotography?You have two options:
1. Afocal projection - an eyepiece projects a virtual image that requires a camera lens (e.g. 50 mm pancake lens for APS-C and 40 mm for full frame sensor).
2. Direct projection - a dedicated phototube (or sometiimes a special projective eyepiece) projects a real image the cone of which can be intersected by a plane which can be a piece of paper or a camera sensor. No camera lens required in this case.
In general every manufacturer has their own formula of what works best and it can be a bit of a minefield so you best bet is to start with manufacturer manuals. Since you are running Nikon objectives on a Leica stand there could be some optical incompatibilities resulting in various aberrations but it might also be totally fine - you have to determine this by trial and error.
