Last Thursday I was in the studio photographing the scars on a person that had been in an accident for an attorney. My Nikon D-100 started to flash ERR, and it only made a clicking sound. So I went out of the camera room and removed the lens and looked inside and low and behold the sensor was laying on the bottom of the inside blocking the mirror from working. I looked deeper and I could see the shutter. The camera is still under warranty (thank GOD). I just couldn't believe that the sensor could fall out, and it had nothing attached to it. I took it back to where I bought it and the owner said "thats impossible, a sensor can not just fall out of a camera". When he opened it up he said "O s#%! the sensor did just fall out". This is just unbelievable, this is the third major nikon issue in 5 months.
1st a lens (24-120mm) that fell apart when the camera that it was on was hanging around my neck, 2nd a SB-80DX that was shooting at full power all the time (nikon sent me a new SB-800DX in place of that, and now the D-100 that the parts just fall out of. Don't stand in under any Nikon equiptment without a hard hat.
