Err+overexposed

**Nikkon** · 04-08-2017, 10:58 PM

Hi
Since a while my d700 with about 50.000 shutterclicks shows ERR (error) in the lcd display and the photos are overexposed. When dismounting and mounting the lens or powering off sometimes I can take 1 or 2 normal photos before the error returns. It does it with various lenses. I cleaned the contacts without result. I suppose I should bring it to a servicecenter but I wonder if at all this is repairable and if it is worth it. Anybody any idea?

Probably the shutter.

If that's the case, it is repairable and not too expensive. Plus you'll have a 0 count shutter.

The ERR is the most serious of the Nikon error messages. Often it means a failing or failed shutter. The shutter mechanism has a self monitoring mechanism and if it finds the shutter timings are wrong, it halts the camera and starts flashing the ERR message. Overexposed pictures could be a telltale of this.

Dirty contacts can cause it too, but you have eliminated this. How about battery contacts? Is the battery ok? I sometimes see the message when shooting fast bursts with an old/depleted battery. The low voltage from the battery is unable to re-arm the shutter, the camera senses malfunction, and halts with blinking ERR. A fresh battery fixes this.

Also a damaged AI-feeler tab on the lens mount could be the culprit.

Too many possibilities to be honest, and some of them expensive. Can you get a free estimate from repair center?
