Hi all My husband has a Minolta X700 that I enjoy using as my 'travel-about-always-with-me' camera. Such a simple gem with the 50mm lens! Problem is that there is some dust trapped in it that is showing up in photos (the sky is a huge problem). I've cleaned the lens, the UV filter, the viewfinder, the mirror and the prism but the debris is still there and it is visiable in the viewfinder. So I'm at a loss as to what to try next. Any ideas? Thanks in advance!
