Minolta MC Celtic 135mm f2.8 Lens Disassembly

Disassembly and reassembly of Minolta MC Celtic 135mm f2.8 lens. Lens is disassembled to access the optics, mechanical sections, and most body sections individually. I wasn't able to separate the diaphragm from the focusing mechanism or remove the aperture blades, but do show how you can clean the diaphragm in the housing. This lens is an interesting cross between the MC 135mm Rokkors and the later MD Rokkors. Cosmetically it is closer to the later MD lenses, and internally it has a more integrated design. For example, the diaphragm is integrated into the focusing mechanism. It still uses high quality components though, and has the more solid feel of the MC lenses. Full time of video was around 30minutes.
