Why does my 24-105 have a different magnification (macro ratio) from a 105mm macro lens at same MFD?

Note that the macro lens you ordered (DN) has different optics than the one shown in the other posts. I am not sure if he has the new mirrorless lens in the optical bench.

Yes, the designs are quite different

Macro 105mm F2.8 EX DG OS HSM

105mm F2.8 DG DN MACRO Art

I haven't located a patent corresponding to the later lens.
This is quite close and I have to reexamine it to see if it's actually a match.
