Two Minolta MC TELE ROKKOR 200 mm lenses have modified to adopt onto Canon EOS Digital mount. QF 200/3,5 heavier lens required more solid bayonet flange avoiding critical optical axis displacement on the connective portion. Self -curing Acrylic Resin material and 4-Metha metallic and engineering plastic adhesive were applied for solid fixation between original SR bayonet nails and added EOS bayonet mounts. Of course the parallelism of flange surfaces are precisely established. The lens element's antero-posterior positions are so adjusted to set acquiring infinity focusing.
Lens testing of them shows a little differences on iris opened condition, the physical property of QF lens is excellent as mentioned in the article, so it worth carrying for shooting in spite of 790 gr heavy lens weight, but it's lighter than Leitz APO-Summicron 180/2 with 2,5 kg?
