    Anyone here see this one? Not the usual problem: "mirror sticks, second shutter press releases it, ERR message". No, this one is a bit more rare.

    It only shows up when you take moderately long exposures, 1/2 second or longer. The mirror flips up, the shutter fires, then the mirror drops back down, blocking the light, so you only get 1/2 of an image. The shutter sound isn't right, there's a weird third "clunk". I'm nicknaming this the "half and half" problem, because it's half a dark frame on half second exposures.

    Anyone else seen it?

    So far, I've found four cases on line, and mine makes five.

    I do have had a few cases of mirror being stuck halfway, or not returning properly. "Rebooting" the camera by pulling out the battery and then re-inserting it has cleared the issue and it must be 6 months at least since this happened. Didn't bother to do anything about it since it's so rarely occurring.

    This one is a little different. It's progressive, just keeps getting worse and worse over time. Pulling the battery doesn't help, but giving the camera a chance to cool down does. The problem seems to be temperature dependent, it's worse on hot days, or after multiple long exposures in a row.

    Hm. Perhaps that's why I haven't been bothered more with this issue - Norway isn't known for its high temperatures :biggrin:

    It's back from repair. This is the second time in. The first time, they kept it for 6 weeks, updated the firmeare, and sent it back, still with the problem. :mad:

    This time, they kept it for 7 weeks. And they just went wild, a "Cat C" repair, new shutter, new power supply, adjust AF, clean the sensor.

    30 shots at 1/2 second, and the problem is still there. :mad: Sent it back again. :frown:

    Aaaaaaaargh! :mad: :eek: :mad: :eek: :mad: :eek: :mad:

  8. Sorry you are still having problems. My D70 has been painfully reliable for about 10K shots.

    I'm thinking about turning it into a "bjorn cam" actually - dedicated IR.

    Bummmmmmmmmmmmmmmmed!

    Count me in on the "mirror lockup issue". (BTW, just turned 27k)

    I've just recently started having a similar issue. After a few shots, and EXIF being ~1/60th @ F5.6... I get the mirror not coming back down, and everything goes DEAD. No LCD... No power in the viewfinder. DEAD!

    Once I pop the battery, and reinsert it, I get the ERR on the LCD. Another shutter click brings the mirror back down, and 2 or 3 shutter activations later I'm back to normal. But one instance took 2 battery removals and a reset. Had this prob happen about 5-6 times today, thru about 80 shots.

    UPDATE: I'm getting this every 5th shot now. And, after reading some other threads, and links... looks like this is not uncommon for the 70. Time to call Nikon.

    Update: Nikon replaced the camera

    After being in repair since July 1, Nikon sent me a brand new, boxed D70 (with all accessories). I thought that was rather nice of them. (well, the one I sent them was clean, with a low shutter count).

    So far, no half-and-half or BGLOD.
