I don't use a macro bellows unit either. I use a Sony E-mount to M39 focusing helicoid. Similar to the one shown here, except this one is E-Mount to 42. These are sold under several brand names, though they all may be made in one place. I purchased mine on AliExpress for $21, plus $4 shipping. I also have one for the Fuji GFX mount.
