Hi I have an old Nikon FM10. For some reason I can't wind the camera. Nor when I press the button will the shutter open or close. And the mirror stays up at all times and I can't see through the little viewfinder.
It sounds like a shutter problem rather than anything else. Should you have any questions feel free to email me at any time our visit our web site for more details www.garryscamera.com. We service this model and can help you out.
