Hi everyone, I have a problem with my Canon EOS 750D. It's strange but I'll try to explain it as best as I can. When I look through my viewfinder it is blurry and has a dark brown layer over it. I can still see some colors and shapes but all in all it's just a blurry brown mush. When I take pictures using the viewfinder (ISO is automatic) the picture is overexposed. When I adjust the ISO myself the picture turns out fine and is not overexposed. Also, when I press the AF area selection button the viewfinder gets a red layer on top of the already brown one. I tried to recreate some pictures of what it looks like when looking through the viewfinder and attached them. When I turn on the screen and take a picture everything works fine. I can also film without any complications and the quality is great. Does anybody have an idea what the problem could be? I wanted to ask before sending it in.
