The proof is in the pudding. Today at work my head Digital SLR technician came to me and dragged me over to his bench to see this. A customer of Mack Camera has sent in their Nikon D1x for repair saying the shutter stopping opening. We hooked the camera up to the diagnostic software and there was 527,200 shutter actuations (shutter releases). The craziest part is that the shutter was good, it was a gear that broke. They don’t make shutters like they used to!
