Lens won't come out

It sounds like the sensor that tells the camera weather the cover is open or closed has failed or come loose. This is a fairly common issue on cameras with the sliding lens covers. Our shop would charge around $50 in labor to fix this issue if it is that sensor. If a part was required it would be somewhere between $20 and $50 depending on what Olympus charges for the part. Cannot speak to what other shops may charge. David Millier Advance Camera Repair

I had a problem with my Mu300. The Lens woudl stay out and would not retract. Battery in and out would not solve the problem - it would jst try to extend the lens further then beep a number of times and shut down. Solution - gave it a few whacks with the handle of a screwdriver - and hey presto??? Hoes that for an engineers touch. PS - no liability is accepted for damage resulting from following this precise and difficult procedure.

Well just remove the lens cover by taking the 2 screws, and glue the switch pull it out and glue it use a very viscose glue, don´t use 3 seconds one. good luck
