Nikon D7100 shutter/mirror problem

    Ok, I sold my well cared for D7100 on the auction site, sent well applied via RMSD. Camera has around 10,500 shutter count. The buyer has come back with a problem .He states that around 50% of all the shots taken are completely black, and also when moved onto his PC. He has tried a different lens but problem is persisting although there seems to be no pattern to it, He goes on to say he shot a couple of hundred images this afternoon using both lenses and that probably 150 are fine, but 50 or so are totally black. The black pictures seem to occur in bunches then the camera will be fine again for a while before another bunch of pictures come out black. Sounds to me like a mirror/shutter problem. Maybe Royal Mail has been playing basket ball with it........

    I'll give it a good look over when I get it back. Anyone know of any recommended repairers before I give Nikon 300 quid?

    Did you set up a non-CPU lens? If so it could be that the camera/lens interface is the problem, a dirty contact. If the camera loses contact with the lens it will revert to the non-CPU lens data and expose accordingly.

    Well I didn't but will investigate on its return. The guy said the packaging was bit battered which it certainly wasn't when it was despatched so Ive asked for pictures of the box.

    Like yourself my initial thought would be a sticky mirror, it's where I would look first as presumably the camera has made the appropriate noises. I did once buy a used Nikon body which only had a shutter count of a few hundred that was suffering in this way.

    I'll see what happens when I get it back. I'll bang a lens on, insert a memory card select ÇH' and fire away :)

    Well, the day after my last post the guy came back to me and said it was working fine so he was happy to keep it. Then a few days later the problem resurfaced so I agreed to have it back. It arrived yesterday so I tried it out this morning with my Sigma 10-20mm and it wouldn't focus or fire at all in any mode. I tried it with 2 other lenses, my 18-200 vr and my 35 1.8G and it seemed fine. I set the shutter mode to 'continuous high speed' and fired it off a few seconds. It's working now with all lenses, including the Sigma so I'll use it as my main camera for a few days to see if I can fathom out what's going on. I'll send it off for a service if the problem persists.

    And....... has the problem gone away or has it returned again?

    Mother has been very ill so I have been somewhat occupied. That said it doesn't seem to like certain lenses, notably my Sigma 10-20mm and my Nikon 17-55mm though they do eventually work with the darned thing. No problems with the Nikon 18-200mm VR. Lens contacts cleaned, reset procedure followed, CH mode used to high degree. I need to properly investigate.

    I am sorry to hear about your mum's health. Hope she gets better soon. That obviously takes higher priority that sorting out the camera.. FWIW my D7100 works perfectly well with my old Sigma 10-20 (lens dates from around 2006)

    Thank you, she's on the mend but at the age of 96 one must expect the odd setback. The Sigma works fine on my D7200. I think I'll keep the the D7100 as my spare body for now. I only bought the D7200 from my friend who was almost giving it away as he was going mirrorless.

    Well, I had another try with it this afternoon. Worked fine with all my lenses initially. Then the issues started again. So, suddenly will not focus or respond to shutter operation. Also underexposes in indoor situations and by 3ev when using flash, exposure ok outdoors. Camera has around 10,500 shutter actuations. I'm baffled.

    Such a wide variety of issues sound like an issue somewhere in the control systems. Probably wouldn't work but have you tried reinstalling the firmware?

    I suppose the camera you got back was the one you sent?....

    No I haven't yet, thanks for that suggestion. That'll be my next attempt before sending for a service/repair.

    Sold it on the auction site. Ive asked the buyer to let me know if he can identify the problem.
