MINOLTA - Minolta 50mm f17 Disassembly

This comprehensive disassembly guide covers the Minolta MD 50mm f1.7 lens, providing step-by-step instructions for complete optical access during cleaning and mold removal. The repair manual walks through lens extraction starting with name ring removal, filter frame separation, and methodical access to both front and rear lens groups. Detailed photography documents each stage—from filter mount and lens mount disassembly through optical element handling and diaphragm assembly work. A critical section explains the structural distinction between front and rear lens groups: external surfaces are protected by hard coatings and can be safely cleaned, but internal surfaces carry delicate soft coatings vulnerable to scratching if exposed. The guide emphasizes handling precautions for small moving parts like click-stop springs and tiny bearings that are easily lost during removal. Complete tool requirements are specified to ensure proper disassembly technique. An optical diagram illustrates the lens design, supporting technicians and enthusiasts restoring this popular economy-class standard focal length for the Minolta manual focus system. This workshop manual serves as an essential reference for anyone maintaining or refurbishing MD-mount optics.
