Dirty Focus Screen?

post #1 of 5
Thread Starter 
Hi everyone, I recently learned that its not okay to try and clean the focus screen with a cloth, goofed it up, and just ordered a new focus screen, installed it, and during the install I must have accidently touched the focus screen while installing it, and have what looks like to be a black fingerprint smudge on the screen, as well as a dust spec that I can't seem to blow out.

Should I worry about replacing it again or just live with it? as i'm sure over the life of the camera ( t3i ) that its gonna get roughed up a little bit anyway.

Picture quality is unaffected.

as long as you can see somewhat clearly using the viewfinder i dont see a dirty focus screen being much of an issue. try cleaning it and seeing if that helps. i dont think it can be damaged as its not nearly as sensitive or fragile as trying to clean your sensor lol

If the screen is glass, DON'T use a microfiber cloth . Lens wipes and cleaner will remove the oil.
