It would be possible to focus, just not to change the focus (extension).
This way you have a fixed focus macro lens. It is usual to focus these
lenses by moving the whole rig, not just by changing the extension.
I'd think a 20 mm lens at a distance of aprox. 80 mm from the film (lens
mounted on body without extension) should give even more than 1:3
magnification. These lenses should'nt be retrofocus type lenses!
