Technical fault not a settings problem

Sounds like the aperture control actuator ring in the camera body is not opening the aperture diaphragm blades fully a repair quote and decide if a different body upgrade may be a better option

Sounds as if the tripod socket in the base of the camera is too shallow for the thread on the QR plate. You can undo the split ring that holds the screw in the plate, and fit a washer beneath it to shorten the protruding screw. What I do is keep a plate permanently attached to each of my cameras and camcorders, so that I do not have to continually remove it to put another camera on.

You need to have the camera serviced. It sounds like you shutter may be sticking and any loose part should be an instant red flag. It had to come from somewhere and it could be related to your shutter delay problem.

try turning the camera off to load when loaded turning on should take it to the counter for no 1 film shot
