As per this video:
Sigma considers a lens suitable for Macro if the image projected on the imager, or film, is at least 1/3 the size of the subject. My example of Sigma lenses here is due to both my Sigma SA9 and SD14 having the SA mount and use the same lenses.
My question is, When does Macro Photography step beyond Macro and enter into the realm of Microscopy ?
I would not mind having a lens, whether for my 35mm cameras or for my medium format Mamiya RB67 Pro SD, that could capture subjects at 10:1, 10X, or even 25:1, 25X. ( At 25X, a 1mm subject would just exceed a 35mm frame )
