Matte Focusing screen problems...

Ok so ive had my Ist*ds for a week tomorrow and and on my focusing screen (i think its above the miror) theres a scratch some how. All i did today was put the lens on and went to shoot and it was there, Any idea on how to fix it my self? Or will i need to get a new one?

Is it a scratch? Or is it a hair or some sort of fiber?

If it's a scratch....don't worry about it.

If it's a hair or fiber....those can be removed. Alternately, don't worry about it.

If it shows up on your pictures it can't possibly be the focus screen. The screen is blocked off by the mirror while the picture is being taken.

How about posting one of the photos here? One of our many resident geniuses is sure to be able to figure this out.

If you can see it on the screen as well it has to be on the lens
It's the only thing that they both have in common.

If you have a scratch or a particule dust in your screen what ever if is outer side or inner side,your not suppose to see the scratch in your picture,if you have one in your picture,its not the screen,should be in your lens or your sensor.

Ok so i figured it out, it was on the sensor. But there also is a scratch on the focusing screen, which doesnt show up. But its better now.

You can remove the focusing screen, use a blower, and see if the "scratch" goes away. I've had to do this a couple of times already since somehow stuff gets in there more often than I would think possible.

If someone would invent a Star Trek type shield that would allow you to mount lenses without allowing any dust in, they would make millions!
