oh dear
made a massive mistake!!!
I thought I would have a go and trying to clean behind my focus screen on my A200 (before I read to leave it alone) as I have had some dust on it for a while, got my tweezers and then pushed out metal clip which went flying and my tweezers caught the focus screen therefore scratching it ARGGGG, I know its a stupid thing to do! I should have left well alone!! I'll never do that again.
I managed to put it back together but no when looking through my view piece it has black marks/spots on due the scratches and dust, I now need to get a new one or send my camera off to be repaired!!
What should I do? Send it off to Sony and get them to fit a replacement one or leave it as it does not effect photos.
It does not show on any of the photos the good thing is that it does not show on any of the photos I take, just through the view piece which is well annoying.
