Modifying to EOS

I want to show how to adopt Minolta MD lens onto Canon EOS mount here. Black ling is from an EOS body cap and a metal ring right side is from Canon EOS body that is utilized as a fixing jig.

The original Minolta SLR bayonet nail 3 in total was ground 0,7 mm avoiding interference to Canon body mirror box upper and lower portions shown as golden colored.

The connection between bayonets are performed with auto-polymerizing resin material and resin-metal-curing acrylic-bond adhesive.
As for the vulnerability of engineering plastic bayonet nails, it is enough for amateur use and it is convenient to be breakable here in case of falling accident, because the stress release would be done here avoiding flange distortion on the camera body.
