Oh no, getting an Err when shooting

[FONT=&quot]I've been shooting with a D750 for a year now. It's been flawless. Starting yesterday, when I first turn it on and shoot, the viewfinder goes black (mirror clicks) and it stays that way. The display says "Err".[/FONT]

[FONT=&quot]After that, I can shoot normally on the second exposure. It's like it is "sticking" the first time you shoot, every time you turn it on.[/FONT]

[FONT=&quot]Has anyone experienced this and is there anything I can check on my side before returning it for service?[/FONT]

I would try doing a factory reset to see if that works.

This issue has been reported by several D750 owners.

It's a sticky-shutter mechanism most likely.

did the factory reset help?

At the moment it is working, but I won't know until it has been idle for several hours. I am skeptical about the software reset because this appears to be a known hardware defect, but I'm going to try everything I can before I send it back. I'll post back if it sticks again.

I was experiencing this almost every day on the first shutter actuation only. Except when I've been in full manual. So now I start out in full manual (no Auto ISO) then switch to Aperture Priority. I'm under the impression it's more of a software glitch based on what I've experienced rather than a bad shutter. But every time it does happen, it makes me wonder what damage is being done. Mine is one of the ones under the initial recall, but I never sent it in. @Blacktop had it happen to him, and even after having his shutter replaced, it continued to happen...hence one of the reasons why I'm leaning towards it being a software glitch.

Not quite. After the first fix, it was fine for about a year. The shutter was literally broke the first time. The second time , it was the light baffle not moving out of the way. Here is a link to the whole saga.

Interesting. Just FYI, our camera never leaves manual mode.

Oops...sorry for my confusion. I thought your problem was similar to mine.

Hmm...so would you consider putting your camera into either Aperture Priority or Shutter Priority just for the first shot and see if it happens? Just curious....

There were two different recalls on the D750. Have you checked to see if your camera was included on either one of them?
