THrough my view finder I've been seeing some hairs. It kind of bothered me. I thought it was the sensor, so I gave the sensor a cleaning. Still there, but moved a bit. However, these 'hair-like' items don't get photographed. They don't show up in the actual image. I'm thinking that they are stuck somewhere in the viewfinder, but I have no idea how to clean it, and I'd like to..since its a nuisance.
