Occassional stuck mirror

[Tristin]

Sometimes when I take a picture, the mirror gets stuck and I get the old "Err" on the top LCD.  Pressing the shutter again fixes it and it is pretty uncommon, but still annoying.  Anyone know some possible causes I could look into?

My old D2X behaves in a similar way. I was told it was a sign that the shutter may have come to its end of life. This camera is IR-converted and rarely used, so I have not bothered to look more into it.

The battery also might be well past its prime.

What camera are you using?

[Tristin]

D750, been in use ~7 months at ~15k actuations, and alternating between two batteries.

How often is "sometimes"?

I remember the Err messages but they happened only every couple of thousand images or so and could have different causes like a dirty cpu, faulty battery, etc.

Tristin: I'd let Nikon service have a look at the camera right away. Better to nip a problem in the bud instead of potentially letting it grow wild.

[Tristin]

Jan, I'd guesstimate that it happens every ~1k actuations.

Bjørn, Yeah, I will.  I mean to get my camera through service before the warrant dries up.  By the way, do you think they will give me trouble for having a third party focus screen?  Should I swap the original back?

Tristin, I agree with  Bjørn and get Nikon to look at it.  I have 33383+ actuations on my D750 and have never had this problem.  I did have the camera lock up one time at around 11,000 but just took the battery out and then put it back in.   My serial numbers falls in the first notification group but have never had a problem.  The Manager of my local Nikon Service Centre and I agreed that I would send the camera up at some point .  I'll wait until I have a problem or at the end of the warranty period (or later, his idea) in case they want to replace a part

Tristin, have you checked the battery in the menu?  In addition to the remaining power, you can check how much the battery is deteriorated.

Since last summer, my D200 for IR shows the same behaviour, but permanently

It does so with external power supply, without lens, with remote controlled, ... everything checked, it seems to be something with the mirror/shutter box.  It started on a very hot day and the camera had been in the back of my car, I had looked for it not getting too warm, but I am not sure, how warm it had gotten. So I wonder, if temperature has an influence on getting this. About 27000 clicks.

Last week, I got another D200 cheap on a camera flee market, about 9000 clicks, ... so I am considering now how to go forward.

Googling around, I haven't found anything (except some people could solve this with new batteries, but I think this is a different problem).

I've experienced my D750 lockup once. Had to pull the battery out to make it work again. Haven't experienced it since.

I can report, that my D200 now ceased to work. The shutter started to stick, so the upper part of a picture was ok, the lower part was over exposed.
Good news: I merged the two bodies mentioned above, took the sensor with the IR glass & attached electronic board into the "new" used D200 and tata, it works, and obviously, all settings from the old D200IR came with the board into the new body. I did not do anything to the AF.

The camera equivalent of heart transplantation? Good on you.

The last IR dandelion stands out amongst a fine set of IR pictures.

[Jørgen Ramskov]

Well done. That's some very nice pictures.
