    Default Dirt spooted through view finder

    Recently, I spotted a few speck of dirt when i look through the view finder of my 400D. However the dirt did not appear at the picture taken.

    Any advise on any cheap way to remove the dirt?

    If you decide to blow your focusing screen, be sure you don't introduce more dust.

    could be on viewfinder or mirror but i would leave it alone..... if you try to blow it.... that could land at worst on your sensor ....THEN it will show up on your end images

    if cannot tahan, bring to Canon Service Center for cleaning

    haha...TS, if it's minor...then probably save up the money and wait for more spots on your sensor then go clean in 1 shot!

    Just a dirt on the view finder, best is to leave it alone. Even if u sent back to CSC they will only blow it with a rocket blower.

    I have that too and tried to clean it with lens cleaning solution. In the end I scratch the view finder, as the view finder is just a piece of plastic that can be scratch very very easily. In the end I had to pay about $55 to replace the piece of plastic at CSC.

    Very painful....

    Viewfinder is plastic? Where did you get this from? The part where the image is formed (a.k.a. focusing screen) is definitely not plastic...

    inside the viewfinder is a prism, made of glass, you won't able to reach it.

    I believe you've scratched the focusing screen, most of the focusing screen is made of glass also, but the surface facing the mirror is the matte side, it will scratch easily.

    same to the reflect mirror, the mirror is front coating, so the sliver coating has no protection, it will scratch easily too.

    if it is dusty, just give a few gentle blows, if the dust still don't go away, just leave it.
    Do not try with any tools to clear the focusing screen and mirror yourself.

    Yah it should be called the focusing screen, I am 100% sure that scratch mark formation can only be coming from a plastic surface ...

    Well i am sure that piece of focusing screen is plastic. even the Ken Rock well concurred with this http://www.kenrockwell.com/canon/slr...us-screens.htm

    Plus CSC is only selling it for 8 dollars a piece so I don't believe that will be the price for a piece of engineered glass.

    This I agree 300% there is not way to clean it yourself except to blow it with a rocket blower.

    Don't try to clean it...

    There is no "better" here, you compare 2 tools for different purposes. Blower should always be the first choice. If there are still stains or finger prints then lens pen helps. Always use blower first, dust can be very hard and act like sandpaper when you rub with any other tool.
