I have acquired an Olympus XA in very good overall condition. Battery check works. Shutter works intermittently. I have dismantled the shutter button mechanism and discovered that one piece, the button release rubber flange (grey) was in fact floating loose in the shutter well.
I also discovered that the button spring seems to be completely flat, with no visible capacity for 'springiness', in the language of the XA repair manual, 'deformed'. See photo of the parts below.
Since the camera does work and is in good condition I have two questions:
- what would be the impact of the missing 'floating' rubber release flange?
- what is the best way to restore 'resilience' to the button spring?
Just by way of a stray thought: is the XA shutter button assembly a version of an early momentary electronics switch? If so ..... then .... !
