A connected Canon EOS bayonet mount on Minolta MD Macro Rokkor 50/3,5 was replaced. The metal part applied was from some jank zoom lens with 2,0mm thickness, so flange back was extended 2,5mm forward. As a matter of fact, too much anterior displacement of lens element made it impossible to adjust on infinity position, this is why I replace the meta bayonet mount into my ordinary way with utilizing a plastic body cap part as usual. The epoxy resin adhesive that had been already applied there was relatively easy separated by heating with alcohol torch. Original Minolta bayonet nail was reduced 0.70mm thickness avoiding mirror box hitting. Thanks to this procedure, the infinity position was acquired safe for this MD Macro Rokkor close up lens. Now I have finished long desired modifications of old lenses into modern Digital EOS mount.
