Minolta MD Rokkor-X 50mm f/1.4 conversion to Canon EOS
Folks this is a 24 minute video, so if you want see full detail on how this conversion is done, then go grab a drink :) I'm pretty sure this is the most detailed-documented procedure on how to convert a Minolta MD lens to Canon EOS. It is of my opinion that the best Minolta SR mount 50mm primes were the MD Rokkor-X 50/1.2 and 50/1.4. By this time in Minolta's manual SLR lens development they had figured out the best coatings, saved some weight and size, and engineered their best aperture diaphragm (hence MD for Minimum Diaphragm). This lens is Minolta's second gen. MD lens. The last and 3rd generation were perhaps just a good optically, but they builds were of more plastic.
