" Reversing Rings
A lens-reversing ring is simply a small metal ring with a camera-body mount
on one side and a threaded ring into which the front of the camera lens
screws on the other. The reversing ring attaches to the camera, extension
tube or bellows, just like a lens. The front of the camera lens screws into
the reversing ring.

Why use the lens reversed? Because standard (nonmacro) lenses are optically
optimized for normal shooting distances, they produce somewhat
below-optimum image quality at close-up distances—particularly edge
softness due to curvature of field. Reversing the lens produces better
results for close-up work, and greater magnification with normal and
wide-angle lenses. "

(Mashol meg arrol ertekezik, hogy az 50mm es kisebb fokusztavu objektivek
adnak jo macro eredmenyt forditva szerelve.Nyilvan itt van also korlat az
objektiv -frontlencse- kalakitasanak es meretenek fuggvenyeben.)
