Nikon’s camera error tied to shutter release often means the shutter/aperture mechanism did not complete a cycle—low battery, cold weather, or a mechanical fault after impact.
Soft resets
- Swap in fresh known-good batteries.
- Remove lens; try body with another lens.
- Power off, wait, retry without rapid burst fire.
- Check for sand/grit around the lens mount.
When to stop
If the mirror stays up or the shutter sounds half-cycled, continued firing can bend blades. Bag it for CLA.
Safety notes
Never poke the shutter curtains with tools. They are fragile and expensive.
