Whats happened here? is this severe?
was shooting some test shots with my 80D and they were coming out quite underexposed. checked my settings and everything seemed fine. changed my lens and whilst i had my camera open i gad a look inside and saw that this small frame appears to have come off on the right hand side. I immediately realised this obviously shouldn't be as it is and was concerned about the mirror slapping it whenever i took a photo. what is this and is it an easy fix?
P.S i'm not sure how long it's been like that. just picked up my camera as i was planning in going out on a shoot and noticed this.
