Wah!! U shot the IPPT thing!! Interesting macro.... heehee..
Neber got to wear one during my time.... cos neber got gold before .... but mostly... the IPPT badge system wasnt implemented during my time. :bsmilie:
basically, i mounted the 100mm lens on the body, and reverse attached the 50mm on the fron of the 100mm lens ie front-to-front. the 50mm lens acts as a very high quality magnifier. drawback is that some lens combionations gives heavy vignetting, and working distances which are too small.
oh, magnification factor if the focal length of the lens on the body divided bvy the focal length of the reversed lens
