Reverse mounting for MACRO

Ok, a couple more results.

28mm lens, normal orientation attached to 65mm tube: Magnification 2.4

28mm lens, reversed on to 65mm tube: Magnification 4.2 (5mm of ruler scale occupies almost the entire width of the frame).

And just to add a very modest, but I'd contend, more practical contribution to the amazing 'IRB test', this was taken with the "28mm reversed on to 65mm tube" configuration:

Not wanting to take anything away from Dan's amazing effort on the other thread, it remains the case, surely , that in any "mine's bigger than yours" macro competition, you have to divide the magnification by the price of the lenses, converters and tubes used, to obtain the true MCC (macro competition coefficient).

My lens was 6 quid, the reversing ring was 12, and the tubes were about 30. So that makes my MCC equal to 4.2/48 = 0.0875. Still probably way back in the also-rans

Thank you, not at all, it's been interesting. Hope you've got something out of it too - if nothing else than that there are lots of options out there other than expensive macro lenses.

And we haven't even mentioned bellows yet !
Bellows unit + extension tubes + 100mm macro lens = almost microscope-like magnification, but very dim viewfinder display and almost zero DOF.
