Hear surgeon Werner? Wow. Impressed. Love the two first shots of the Poppelsdorf series. Lived there for 8 years, met my wife there.

As no-one has mentioned firmware yet, I'll do it. Maybe it is a bug, haven't read all the things they fixed in the firmware updates.

Tristin, you are apparently not the only getting the "Err" messages with the D750

I believe I have experienced that with my D750 once. Had to pull out the battery to get it working again.

This has recently happened to me, I've had my D750 for about 18 months with zero issues.  I recently purchased a 58mm f/1.4 and a couple times this past week I got the ERR message and had to power off/on camera, press the shutter release again and it works fine after that.  Kind of disturbing because no issues with the D750 until now.  Turns out that this only happens when I first turn on the camera and with a 1/4000 shutter speed.  I can replicate this easily, by shutting off the camera for an hour and then taking the first shot at 1/4000.  And have done this with multiple lenses.  Apparently not an uncommon issue: http://www.digitalrev.com/article/nikon-d750-fast-shutter-speed-crashes-camera and there are plenty of other people complaining about this on the web.

From what I read online the remedy is to send the camera in to Nikon and have the replace the shutter assembly.  This seems like it is common enough to be a service advisory/recall kind of issue, but for whatever reason it is not.  Kind of a bummer.  Some people have sent it in have received the camera back and the issue is not remedied.  I agree with Bjorn that to send it in sooner rather than later is best, so I sent a message off to Nikon today and will see what they say.

More info: https://petapixel.com/2016/04/26/nikon-users-reporting-yet-another-shutter-issue-d750/

This issue seems to be well known for at least a year.  The serial number of my camera is not part of either of the official recalls, but that is not uncommon for this issue.

Thanks for listening.

Footnote:  The ERR message can be avoided by making sure the first photo taken at start up is at a slow shutter speed.  1/4000 for sure will cause the ERR message.  It is the same with me as with Tristin, a second press of the shutter release solves it, although sometimes I have to turn the camera off then back on.  From what I read online the only way to rid yourself of the issue is to send in the camera to Nikon for a new shutter assembly at a cost of about $250 US Dollars.

Feedback:  Do you think it is worth sending in?  My worry is that over time other damage could happen to the shutter mechanism or what not.

Thanks.

I tried to switch my D750 on, set it in M mode, set the shutter speed to 1/4000 and released (this was the first shutter release after switching on).  Voila!  I could see Err message.    :o :o :o

It happened to me a couple of days ago for the first time. Three times in a couple of hours. First i tried to remove the lens as i was using the new 70-200e fl fit the first time. Then, as with every one else, just shutting again solved the problem.
   I can not reproduce the err with the 1/4000 method so it remains completely random in my case. It has not happened again

My D750 exhibited all the symptoms listed above prior to having the mirror box replaced under warranty.

It would also lock up with the mirror half way up. In these instances the only thing that would restore operation was physically pushing the mirror down...powering off/on or removing the battery would not release the mirror.

Nikon finally issued a service advisory for the stuck mirror issue:  https://petapixel.com/2017/07/14/nikon-recalls-d750-third-time-shutter-issue/

Good news.  (I think this is why they installed a new shutter assembly no charge for Tristin recently)

My D750 turned out to be one of the affected bodies mentioned in the service advisory issued two days ago.  I took mine to Nikon service yesterday.  Hope the mirror lockup problem will be addressed along with the shutter problem.

I agree Akira.  Maybe Tristin can test his?  From a fresh boot (camera should be turned off about an hour or more) take first shot at 1/4000 and see what happens....
