I was taking photos and suddenly a black strip appears on the pictures. Then I realized that something was wrong with the camera, some mechanism was not working.
There is something stuck when the picture is taken. When I set the on-camera viewer I can see a black band or belt blocking the light as you can see in the following image
Is there a way to fix this easily? (I would be willing to un-mount the camera to check and repair it if someone guides me).
Do you recommend that I send it to some technical service?
How much can it cost to fix the camera?
