This is one for you (more experienced) camera people. I reluctantly let my elder brother take my Canon EOS300 to Kenya with him while he went on holiday. Despite telling him not to do anything to it other than take pics, he tells me he has tried cleaning it. OK, I thought, fair enough, nice gesture. However, realising that he doesn't know that much about them it worried me when he told me he tried to clean the mirrors inside. Having looked at it myself (I profess to being no expert) I fear he may have permantly damaged it. When looking through the viewfinder you can see smears around the edges. I looked inside and although the mirrors look clean you can see smears. Having looked at his pics it hasn't seemed to affect them, but I do fear that it may be busted.
Anyone got any tips?
Would it be worth taking it to my local camera shop for some advice?
Please, someone help me as it is the second most valueble thing I have and I can't really afford to replace it.
