Question about Nikon Photography
I have a Nikon FM2n that has developed an issue that only happens when the camera hasn't been used recently. This can be a week or just over 24hrs. The issue is when you wind the film on - the shutter will automatically fire as if it was taking a photo which will result in a wasted frame on the roll of film. I have recorded a video of this happening and it is when you have wound the lever all the way on then when the lever is on the way back after the full function of winding the film on has been completed - the shutter will fire. When you go to wind it on again, it will behave as per normal.

It is very dangerous though... [referring to Alexander's solution]... I've been shocked more times than I care to really admit, and that cap can cause some serious damage. Be careful!

Not necessarily. The EM has an M90 setting which will fire the shutter at 1/90th of a second. The meter is inactive on this setting. It was put on the EM so that if the batteries fail, you can shoot at 1/90th and take a guess at the exposure. There is also a small button (blue or chrome, depending on the production run) which lights up a red LED if the batteries are good. The light meter doesn't work until the frame counter is at 1 or higher. Before the #1, the shutter will always fire at 1/2000th of a second to speed up the film loading process. You can tell that the meter is working by observing the meter's scale/needle on the inside of the viewfinder. If it is pointing out of the red zone, it's OK to shoot (proper exposure). If the needle is in the red zone (indicating under or over exposure) the camera will "beep" as an audible warning. Check the battery condition first.

Hello. 35mm cameras back in the day used to suffer from this irritating problem. There is a small button that is pressed by the door edge when you close the back. Due to age(flexing and slop) that occurs with normal wear, the metal edge becomes ever-so-slightly bent, resulting in a less-than-needed pressure on this button. The button, when held properly by the back, captures a little internal gear mounted on the film counter dial--preventing its spring-loaded return. When you remove the back to re-load film, the counter immediately jumps back to "start". As the film advances, the roll increases in size and pressure against the door, causing the symptom. Go to a camera store with knowledgeable sales people and you might find one who knows how to re-work the back just-so to fix it. To be absolutely sure, however, you'll need to buy another back.
On some medium-format cams, there is a little raised "bump" on the edge of the door that precisely matches up to the position of the button. If this is the case, and you are careful, it can be gently but firmly squeezed to make it stick out more, increasing the pressure on the counter button.---Rick
