Hi folks: I would like to take the Pentax-M 50m 1.7 lens apart to try clean up the internal dust and what looks like mold or some kind of spots on one of the internal rear lenses. Are there any tutorials or instructions on how to take this apart? I've taken apart Fujica lenses, but never one of these.
scroll down 7 messages to the one about Takumar calibration - there's a link there to a good site on lens service. it's for an f/1.4 Takumar, but as I recall the M series were built similarly to the Takumars.
