The stain is from the shutter bump stop rubber. As is ages, instead getting harder like a lot of rubber does, it softens and turn into a goo-like substance that starts to smear the shutter curtains. It will eventually cause the shutter to misfire (not open) from time to time. The problem will eventually get worse until the shutter stops working. The fix is a new bump stop rubber that costs about $5 or so - the bad news is that to replace it requires extensive disassembly of the camera and is quite expensive. I had quotes to get it done and it was around AU$150 (US$100 or so) to fix. Most if that is labour costs. Any qualified repairer can do the fix. You can clean it off (to an extent) yourself using alcohol based cleaning fluids/solvents and a cotton bud. There are 3 main problems with this: 1. cleaning the back is easy though the film door, but a shutter has 2 sides. The goo gets on both sides of the shutter. The front can only be cleaned by locking up the mirror. With an RT, you will find it pretty difficult to get to the front due to the fixed mirror. 2. without replacing the rubber, it'll just start to smear again when you use the camera. 3. if you're not careful you can damage the shutter blades resulting in an even more expensive repair. Carefully cleaning it yourself WILL delay the inevitable repair. Cheers Gary This message has passed through an insecure network.
