ERR
Nikon Camera
Severity: CriticalWhat Does This Error Mean?
ERR on a Nikon camera is a general error indicating something went wrong. Unlike Canon, Nikon does not give specific error numbers on most models — just ERR. Start by removing the lens and battery, cleaning contacts, and reassembling.

- Shutter or mirror malfunction
- Internal electronic fault
How to Fix It
-
Turn off the camera, remove the lens, and clean all contacts.
Clean the gold contacts on the lens and camera body with a microfiber cloth. Dirty contacts are the #1 cause of ERR on Nikon.
-
Remove and reinsert the battery and memory card.
A full power cycle with battery removal clears temporary electronic errors.
-
Try a different lens.
If ERR only appears with one lens, that lens has a problem. If all lenses trigger ERR, the camera body needs attention.
-
Try a different memory card.
A corrupted or slow card can trigger ERR during shooting.
-
If none of the above works, the camera needs professional service.
Persistent ERR with all lenses and cards indicates an internal fault.
Frequently Asked Questions
Why does Nikon only show ERR without a number?
Most Nikon cameras display a simple ERR without further detail. Some newer models (Z series) show more specific error messages, but the classic DSLR line uses just ERR.
Is Nikon ERR the same as Canon ERR 99?
Similar concept — both are general catch-all errors. Both are most commonly caused by dirty lens contacts and are fixed the same way.
