Hi 
this morning I tried a Fujica St605 and the shutter button remained stuck at the bottom when I pressed it, why do you think?
the camera is unloaded, in the sense that it had not been loaded to take a photo and there is no film inside.
now how can I get it to return to its position?
if you try to wind it, to load the shutter, it is not possible because it resists and I tried imagining it was stuck.
