EDIT:
Garbz, you were absolutely right. I managed to unclip the focusing screen and the shim and used a small blower to remove the dust. However, I foolishly cleaned the focusing screen with a cloth. There are many many grooves on the screen that hold onto the dust. Does anyone know how I can clean the screen? Where can I get a replacement? I looked on Adorama and B&H but they only have focusing screens for the D3, D2x, etc.
Also another question, what is the mirror that "folds" into the reflex mirror? It seems that there is a a smaller one underneath the larger reflex mirror.
Thanks
David
