I ordered an Olympus XA2 from Amazon and put two rolls of film through it. The shutter stopped working and the film will not wind. Pressing the shutter reIease button will activate the self-timer but the shutter still will not fire. I am in the process of returning it but I am wondering if this is a common problem on these 30+ year old cameras. Am I wasting my time in trying to find an XA or XA2 that will hold up to continous use? My sense is that there is a bad chip or other electronic part and that it probably cannot be repaired or replaced because the camera is so old. Has anyone else had similar experiences with these cameras?
