I have a Canon EOS Rebel T7 I got as a gift within the last 5 months. This is my first camera and I'm looking for help. I hate recently had these fuzzies all over in my shots. It's not the sensor, I've cleaned that and it could be my mirrors but I've tried cleaning those. The dots show up in pictures and it ruins them. I have an air blower which doesn't help, microfiber cloths, and sensor cleaning swabs. I have no idea what to do and I need help.
Solved! Go to Solution.

There’s only one visible mirror. So that mean you also scratched the focusing screen above the mirror.

Are you sure it’s not the sensor please post an example picture in the forum. How did you clean the image sensor exactly. Do you see this in the viewfinder too.

Excellent follow up questions.

If the dots are showing up in photos, the mirror is NOT the issue because it is not in the light path during image capture. Spots in images would be the lens or sensor, as the other forum member stated: post some images.

The only thing in the optical path when a picture is taken is the lens, shutter and image sensor. So the reflex mirror is out of the way.

Yes, I do see this in the viewfinder. There are a lot more than that are visible though this picture. I cleaned my sensor with a cleaning swab (Yes one meant for cameras) and sensor cleaning solution. There are many more dots in the viewfinder than show up in the images.
I have a hunch it could be my shutter? Because I've tried cleaning my mirrors lightly with lint free microfiber cloths, and air blowers to no avail

No you have dust on the image sensor. The viewfinder has what’s called a focusing screen. Did you clean that if so it may have been scratched. The focusing screen and mirror ARE NOT part of the optical patch. When a picture is taken the mirror moves out of the way. Also DO NOT clean the mirror it’s very fragile.

Send it ti Canon for a cleaning and tell them the problem.

here's a better example.

That's where I messed up then, because i have cleaned the mirror with multiple surfaced probably shouldn't have, but I've cleaned the sensor multiple times, nothing helps though??
