I have had this body for years and it's always been flawless until today. The exposure lock button is stuck in the engaged position, it is a button I only use on occasion. Decoupling and coupling the AE AF doesn't do much as does repeated depressing of the button. I have been looking for diagrams or howtos on taking this section apart to clean the contacts before hunting for another body. I'm also unable to find a repair shop willing to diagnose the body or it will just be cheaper to find another body. Regardless, if anyone has any insight, I would appreciate any information. Thank you.
