I recently bought the Nikon FM 10 manual SLR camera. I'm a complete beginner so I hardly knew what I was doing with it. I put in the batteries and followed the instructions to test it out. I moved the film advance lever to the ready position and then pressed the shutter release buton. The three LED lamps lit in the viewfinder. After that, I fiddled around with the lenses. I zoomed in and adjusted the focus and so forth. Then I tried out my seperate flashbulb that I had bought. I don't know what happened after that, but then the film advance lever got stuck in the ready position. I won't even go back to the original position now! And also, now when I look into the viewfinder and press the shutter release button, the lamp lights don't go on! I changed the batteries twice but nothing happened! I don't know what to do! PS- my camera has no film in it.
