Okay, so I tried the rubber ring trick to remove a filter with a dent in the ring. No go. The lens is a 55mm Super-Tak attached to a purchased Asahi-Pentax S-1a. When I try to move the deformed 49mm UV filter, the focusing barrel of the lens starts to back out of the lens body, so my fingers cannot stop the barrel and the filter will not budge. In my humble opinion, no plastic filter wrench will work on a deformed filter ring.
So my question is whether the Super-Tak is worth the trouble? Second question is what about the loose focusing barrel, probably created by the original owner. Third question is can I de-glass the UV filter without damaging the lens objective?
I got this package on an eBay auction for $27 simply for display/wall hanging. So I did not have high expectations. Surprise, the body is immaculate, shutter works, film advance lever works. The S-1a is unmarked, was in a leather case, and shutter curtains are smooth in operation. So now I suddenly want to buy a roll of film.
BTW, there is a lot of dust visible through the viewfinder. About half is in the Tak, based on viewfinder after removing the lens. this may have resulted from previous owner's attempts to remove the deformed UV filter.
Any easy fixes or should I test the camera with film and if it works, get another M42 Super-Tak?
This camera is exactly like my old Yashica from the early '80s, so it feels nice in my hands.
What is the best method for removing dust from the mirror box and prism. That is an added question!
