Viewfinder Blurry, Images Sharp
Hi everyone! My Canon t3i's viewfinder is super blurry. I've tried adjusting the diopter and that's not the problem it seems. When I look into the diopter from 4+ inches away I see a black rectangle that looks to have fallen out of place. As I place my eye to the optical viewfinder, I no longer see the rectangle but it's totally blurry and nothing is in focus.
My images are still great but I'm unable to use my viewfinder to take photos which is a bit of a pain, since I can't effectively manually focus. A photographer friend of mine mentioned that it looks as though the "seal" has come undone and told me that the object is the reason for the blurriness.
any advice as to how to open my camera to find and fix whatever object is in the way?
