MD 75-200 on EOS



0,30mm step on the outer circle of the flange surface and removing the lens-back adjusting sim 0,2mm could have eliminated the discrepancy of flange back difference between Minolta, 43,5mm and Canon EOS 44,0mm. So, no complicated lens element or lens mount case length adjusting were not required on New MD Zoom 75-200. Following my selfish and fixed perception on the magnification of focal length, the less magnifying F/L, the more physical property and performance of zoom lens would attain, this 3 times variable F/L MD 75-200 might have superb performance on earth. I'm looking forward to try this tomorrow.
As shown in the upper descriptions, lack of flange-back value of 0,5mm makes it impossible to focus on the infinity point if used on 44,0mm Canon EOS Digital mount, so most of superb Minolta SLR lenses while silver salt film period are deserted as voids in the market, but actually they are all available if tried to adjust for matching the different construction on flange-backs each other. This kind of hobby works on lens adaptations are not guilty, because the work itself is not destructive but constructive to survive the lives of wonderful industrial products like a phoenix. I should not be denounced but be appreciated.
