Pictures coming out blurry

[rlangton]

Canon EOS Rebel SL2, pictures have started coming out very grainy/blurry.
I don't get why, this camera and lenses used to take crisp, beautiful pictures. I'm trying different lenses, I have an EFS 15-55mm and an EF 85mm. Auto focus is on for all lenses. Stabilizer off. File quality is L.

Welcome to the forum.

Go into the menu and reset all camera settings.

Set camera to green square auto and take an outside photo of your home in good sun. 

If it is still not right post the image so we can examine it.

I don't see an option to reset all settings, where is that?
The picture size is 11MB, this forum only allows uploads up to 5MB. Should I lower the quality in the camera settings before taking a picture?

Had to turn the quality from L (with a curved symbol) to M (with stairs symbol) to get the file size < 5MB

The image you posted looks fine to me.

Is it just a matter of lighting then? Something else? Maybe it was because I was using the P setting?

Merry Christmas.

Blur often comes from having a slower shutter and grain often from using a higher ISO.   Your last indoor image has a wider depth of field, so the aperture I'm guessing would be around f/4 or smaller?  Then to compensate for that, the shutter would be slower and/or ISO increased.

You could try the Tv mode (shutter priority) where you tell the camera what shutter speed to use.  Just a guess here, but try at least 1/100 seconds or perhaps faster.   The camera will then adjust the aperture and/or ISO to balance things out.

Or, if your lens has a wider aperture (e.g. f/2.8), set to program mode and choose that widest aperture plus an appropriate shutter to not be too slow.

It looks like the antlers are sharper than the face of the girl. Do you know which focus mode you were using?

[rlangton]

Touch focus on the mini screen.

I think your biggest issue with the indoor shot is low light and the corresponding high ISO of 25600.

The outdoor shot of your home is great.

Here are two comparisons for noise evaluation for the SL3; one version newer thatn your camera.

ISO 100 (same as your outdoor shot)

ISO 25600 (same as your indoor shot)

You can see how grain and loss of detail has developed.

Your indoor image used the Portrait Picture Styel and had High ISO Speed Noise Reduction enabled. Both of those features serve to reduce apparent sharpness. 

Left image is with High ISO noise reduction. Middle image is in-camera JPEG with camera processing applied. You can see how noise was reduced, but detail was also reduced.

I say there is nothing wrong with your camera.
