It's not so much that I want to 'clean' it, there is this like really small particle on there and all i'd have to do is like get rid of that SOMEHOW. I know that, that part of the camera is very sensitive and fragile so I want to be careful. Is it a bad idea that I do this on my own or should I take it to the shop? If it is possible doing it at home (while being very careful), how should I go about this?
