D750 Shutter Issue - Reproducing it Consistently

[dwf]

My D750 was exactly the same, leave it for an hour or two, make sure the shutter speed was over 1/1000th of a second, and the first shot would always generate an 'Err' message. A second push of the shutter would clear the problem and the camera would work correctly after that. There appeared to be no damage to the shutter, and it wasn't a serial number affected by the recall. The camera had around 4,000 exposures and is about 18 months old.

It wasn't a big problem, I only noticed the issue because I went to France and took photos in the mountains with fast shutter speeds, it may well have always had the issue. When I bought it (in the UK) the camera could be registered with Nikon to extend the warranty for a second year. I sent it in as I'd rather get it fixed now rather than have the shutter fail in a years time and have to pay to get it fixed. It was back in 3 weeks with a replaced Shutter Plate Unit, and the problem has gone away.

Good stuff. Glad you got it fixed. The primary purpose of my post was to help people diagnose this shutter issue early. Seems like you used a similar method, good to know.

Cheers

Process

1. Let the camera idle for an hour. On or Off don't seem to make a difference. Your time may vary.
2. Change the ISO or Aperture to ensure shutter speed of 1/2000" - 1/4000". The lens does not seem to matter. It has happened with a 14-24, 24-120 f/4, 80-200 f/2.8 all Nikons.
3. Take the shot. The mechanism locks with the viewfinder blacked out.
4. Next shot clears the shutter and the camera operates normally from there.

I have had it same for a week then shutter failed completely (it was around 12000 clicks). See here:

Nikon repaired it for free (it was gray unit, also its SN was not indicated as affected on Nikon site).

You may get an err if you'll let it rest for few hours than shoot at high shutter speed. This is my experience.

My D750's shutter issue. My D750 started doing this 1-3 times out of every few hundred shots. Didn't think much about it. Started to increase to like 5-10... Now, it's like almost every other click. Tried new batteries.. Took off grip.. Tried different lenses.. No luck. I said, "F nikon" and moved on...

Nikon quoted me almost $500 to repair it. Screw it. I sold the junk on ebay as parts for that price. It's like buying a new car and the transmission crapped out at 20k miles and you're forced to pay for the repair..
Looking at Sony at the moment..

My camera is in for repair and this post is to perhaps help others that may experience intermittent Err issues with the D750.

Background

Had the intermittent Err issue come up on my D750. The camera would fire but the shutter would stick, the viewfinder was black and the picture recorded was black. Next shutter press would clear the issue. Had this happen 3 times out of 1000 actuations, small probability.

Needed to get it to repeat consistently so I could send the camera in and get it repaired. Nikon may have taken it anyway and done the right things to fix the problem but I needed to be sure.

Process

1. Let the camera idle for an hour. On or Off don't seem to make a difference. Your time may vary.
2. Change the ISO or Aperture to ensure shutter speed of 1/2000" - 1/4000". The lens does not seem to matter. It has happened with a 14-24, 24-120 f/4, 80-200 f/2.8 all Nikons.
3. Take the shot. The mechanism locks with the viewfinder blacked out.
4. Next shot clears the shutter and the camera operates normally from there.

Hits the issue every time with my camera. If you are experiencing an intermittent Err issue, this should help get a definitive answer. A glitch that is cleared or something that needs attention.

Hope this helps you. To be clear I love my D750, nothing has changed except hope to get my camera back so it operates without the Err issue.

Have a good day.

Thanks for bringing up this issue. When I found out that my d750 serial number falls under the latest shutter advisory ( even though it was clear in the earlier flare advisory) I was thinking that probably my camera does not have the shutter issue. I was thinking of waiting to see if I ever encounter this problem before I send my camera to Nikon. Now I know that I have it. It is exactly the same as you mentioned. I tried clicking at 3200 shutter speed and shutter froze and showd err. On next click and later it started working normal at various shutter speeds.

As you said I will check again after sometime. But now the camera is going to Nikon for sure.

 

[fkazmi]

Yes. Mine is grey market and is on the list.

Am pleased it was helpful. Cheers. Take great pictures.

I heard that even if you had to pay for a new shutter before the recall, it is possible to reclaim your service charges now that the problem is a recall and Nikon will refund your costs!

 

[Donalan]

....

Do this, gather evidence, then contact Nikon and tell them you want the camera repaired for free.

Good idea. I've tried it twice. I twice sent them emails with links to the many many threads here and similar descriptions on Petapixel and mentioned that they must certainly know about the problem by now. I asked whether a repair would cost me, since my camera was out of warranty by a few weeks (the first time) and not on either list (the second time).

Both times I got back a corporate-speak answer ignoring all the evidence and directing me to send it in for service on a normal full charge basis.

I have yet to send it in because I am so annoyed. Predictably, my investment in lenses is keeping me in the brand. But I'm sure that someday I am going to have a brief chance at an amazing shot and forget to clear the shutter first. Meanwhile, it is not certain I would recommend Nikon to a friend. They would probably fix this if they were not in some financial peril.

Need to find out about this .... thanks for posting.

For anyone still following this, I too had the dreaded Err message with locked up mirror. It was under warranty so I sent it in and they replaced the shutter. Fast forward one year and perhaps another 5,000 clicks, and it happened again! But this time it was not under warranty. And since they already replaced the shutter once, it doesn't come up on their "list" of defective shutters. So I now sent it in a second time for repair and asked them to replace the shutter for free even though it is no longer under warranty.

For the exact same failure to occur in a span of a year, really?? What is going on over there at Nikon? This is what pushed me to mirrorless.

If anyone is still interested in this this thread, I'm happy to update you on what they end up doing.

Don't they have warranty on repairs where you live?

As everything else can happen, why is this not supposed to?

Don't mirrorless cameras have shutters?

If it keeps you happy, that alone will make me interested in the thread.

 

[Missouri_Skies]

For those of your that contact Nikon about issues this, to whom do you send the e-mail? So often I find an e-mail address and it just goes into a black hole never to be ween again.

Thanks,

Yes, and if you read my post, you would understand it was out of warranty.

Because when the same failure happens twice in a row, it means it is not really random and therefore suggests an inherent design or production problem at Nikon.

I have a Sony A9: in the last 5,000 images I have taken, the mechanical shutter fired off exactly ZERO times.

If it keeps you happy, that alone will make me interested in the thread.

I would be even happier if you didn't respond to any more of my posts.

This is horrible. What did you do?

 

[ShKen]

Hi, I wrote to Nikon Europe, nag nag nag and got shutter replace for free.

 

[DAVID MANZE]

Grey market D750, received the camera repaired, new shutter, new optical viewfinder screen (yeah, I asked for nothing screen wise) and new rubber grip.........grey market....all free inc. postage both ways...

Like how bad is that?

 

[ShKen]

Kudos!

As far as I know, part of Nikon service in many cases (hence the price tag for every repair) is replacing the rubber parts and checking the camera. I don't know how that works for the grey market where you are located. Anyway, good luck with your renewed D750. Hope you'll (we) be able to use it until the Nikon D950 release YellowSmileyFace.

Thanks! I'm in France!

Not sure what Nikon's "yellow smiley face" is, but I'm sure it's good.
