I have a 300 f4 SMC Takumar (m42).....with a problem. Glass is perfect, but the focus was odd...I turn the focus ring such that the lens body came right out the front! Good news: it appears no harm was done to any part of the lens, and the helicoid threads look fine...bad news: I have no idea how to re-assemble. I believe I need to remove the focus ring/rear threadfs from the rear lens body, screw that to thw front, then re-attach the works back on the rear. Not sure if the three very small sloted screws in the focus ring retain it to the rear unit?
