Asahi Opt. Co., Super-Takumar 55mm f2 Lens Disassembly

Full disassembly and reassembly of a Asahi Optical Company (Pentax) Super-Takumar 55mm f2 lens. Lens is disassembled down to access the optics, diaphragm, mechanical components, and body sections.
This lens is pretty easy to repair. You can access the diaphragm quickly and remove it fully from the lens for cleaning. It does use a few cheaper components, mainly a thin metal strip glued in place for the focusing indicators, but this is only a very minor annoyance.
Full time of video was around 30 minutes.
