The oily innards of a camera.

[nzoomed]

wow thats alot of work to clean that thing up and re-assemble!

Unfortunately, there is a broken part in the shutter. There should be a pin sticking out, where the arrow is pointing. This is the mechanism which sets the shutter speed.

Thats crazy, I dont even know how people manage to design these complex and intricate mechanisms!
So many things to go wrong.
My olympus XA3 had seen some rather rough abuse when i got it, and found the film advance wheel would lock up and not allow you to take a picture, turned out some of the plastic housing had broken, but a simple fix by gluing it back with super glue and its never missed a beat since!

Olympus has made some of the finest cameras in history, cant remember the guys name, but their chief camera designer was behind many of these models right from the 1960's through to the 80s.
Whats great about these XA series cameras is they are a great compact film camera to take anywhere that fits in your pocket and doesnt look out of place anymore than a disposable camera, and they take great pictures with an accurate enough meter to expose kodachrome!
