I continue my "Nikanon" project.
I assembled manual bellows with a Canon body mount and Nikon lens mount for macro photo.
It is one of test.
Model:My little friend(Face width:about 10mm)
Result:I can catch my friend face about full size of a APS-C pic(24mm).
so I can expand object 2.4x :).
but using 55mm lens, working distance is very close( about 20mm from top of lens).
when I want more long working distance( about 120mm ) I will use 105mm lens.
Of course no electronic connection, no lens data on original EXIF.
