viewfinder - Why does Nikon D90 makes strange sound and shifts Mirror in Viewfinded Eyepiece after Shutter-release button is pressed


Recently I have noticed that my Nikon D90 makes a strange sound and sort of shifts mirror up if you look at the viewfinder eyepiece after you release the shutter-release button.


If you try to shoot it via Live View, you don't see this issue at all.


It only happens when you try to shoot without live view, you literally can see in the viewfinder eyepiece that something(probably mirror) shifted a little to upward position, plus you can hear a short noise when it gets shifted after shutter-release button was released.


Did anybody had this kind of issue? Any solutions about fixing it?


Thanks.


I guess I wasn't quite clear in my explanations. The thing is, the flip-up mirror, literally flips up a little bit(probable several milimeters), after you took a picture. So what you see in the viewfinder after you release the shutter, is that the area that you see gets shifted upwards, kind of like your mirror got stuck somewhere, and then shifted to it's original position. Plus the strange sound is still there after you take a picture using a Live View. Did anybody had this kind of issue? I'm not sure it's a hardware mulfunction or not. I had this camera for 3 years, and never encountered this kind of problem.
