A year and a half ago I bought this from the previous owner and never used it. The owner had taken extraordinary care of the camera and was very knowledgeable about all parts that came with it. I haven't touched it and I won't pretend to know much about cameras. Some dust has collected and I'm sure it needs to be cleaned. I took pictures from all angles and it is still in excellent condition. I am clearing out things I don't use and this is one of them.
