I thought I would update my original post to mention my problem.
Throughmy viewfinder on my Fuji S3 Pro I see a small hair at the bottom pointing half way up... Theres also specs in view. My ccd is spotless & I have traced it to be on the focus screen but on the reverse side. I know the screen is held in by a thin metal bar. Does anyone know how easy it is to pop it out & to clean? I have had this problem for ages now and dont like the idea of sending it away to be cleaned. I sent my Canon camera away to be cleaned just over a year ago and after 4 weeks it arrived the same as when I sent it. Any help or advice would be great
