Hello /p/,

I recently purchased a Nikon F3, it was working just fine. After I shot my first roll of film full I took it out and didn't put in a new roll because I got a new lens and wanted to test it out. However the shutterspeed is now stuck at 1/80 and it doesn't change when I point the camera at a light.

Thank you in advance for your help.
