Mechanisms will rust/spoil through lack of use. It's a good idea to play with your flash/lens/camera once a month. I recently just took all my flash units and film camera out to just warm them up as... and good thing I did. One of my film camera was acting a bit erratic (FEE error, cannot close shutter, etc), but after trying for a while, the mechanism smooth out and became functional again. Ditto for the flash units.
My friend at one time have 5 nikon F3HP. Which 2 of them he don't use at all. When he try to sell them only to find one of them not working. Then sent it to shirro, the tech told the camera just die because he don't use it.:what:
We might have all heard of a term, 'Death due to neglect', but I couldn't say for sure if it afflicted such devices. A website describing various older film cameras tells of shutters getting 'sticky' with disuse, but it will warm up after doing a few dry shots.
1. Store in a cool dry place.
2. Remove batt to prevent leakage.
3. Take the camera out at least once a month and operate it.
4. Every one - two years bring it for inspection by original retailer or Nikon Service Rep.
5. Service every three - five years.
