Is my 550d body faulty?

Hi,

I have an old 550d body and recently returned to photography after a long break. What I noticed is that some pictures are blurry on my Sigma 30 1.4 art wide open. I started taking some more pictures using other lenses and realised that, depending on the lens used, some images are just unusable. I don't think a case of missing focus or camera movement as if the image is blurry it's not sharp along the whole picture and the shutter speed is more than enough to compensate for any kind of movement. It's especially visible on my Sigma prime lens. I'd say that around quarter if not more photos is blurry. Below you can find both sharp and blurry pictures taken in quick succession on:

Sigma 30 1.4 Art

Canon 50 1.8 STM

Sigma 17-50 2.8 HSM

Here's a link to the full album: https://www.dpreview.com/galleries/4966558671/photos#page=1

So my question is considering that this thing happens on all my lenses, could be a faulty body?

Thank you for your answers

Are the pictures sharp in live view shooting mode. If yes then there could be dust in the AF sensor. Makes sure Quick AF is OFF while testing live view shooting.

I checked an EXIF info and the reason is apparent. Stop the lens down from f/1.4 or f/2,8.

You don’t need shutter speed 1/1000 for shooting houses, unless earthquake takes place

Don’t hesitate to post pics from re-test, we can say more, then. Using blower is meaningless.

I tested it at f5.6 and f8 and it's still noticeable.

Checked the liveView mode and all 20 photos I took were tack sharp wide open. Tried to clean the AF sensor with a blower but it didn't help. After cleaning 4/5 were blurry

Can you post some pictures with the lenses you used stopped down.
