There have been few posts since I did some bad deeds to my camera. Actually, I have been trying to get rid of a spot and in my frustrations I managed to make it much worse. Here I have been thinking I was doing the right thing by very carefully using optical paper to clean the lenses and the mirrors. The spot did not go away. It became two. Then one black blotch. Then one black blotch and a spot. And, finally, a black blotch, a spot and a wavy line. Alas, the camera is back at the fix-it department of Nikon. I hope it doesn't deplete my budget. I miss my camera but will go back to the old one until the other is returned home.
